'''Worsted''' is the name of a [[yarn]] and [[cloth]] usually made from [[wool]]. The name derives from the village of [[Worstead]][[www.worstead.co.uk]] in [[Norfolk, England]]. The village became, along with [[North Walsham]] and [[Aylsham]], a centre for the manufacture of yarn and cloth, after weavers from [[Flanders]] arrived in Norfolk in the 12th century.

* Plastic canvas is a lightweight plastic material with regularly spaced holes in imitation of embroidery canvas. It is also commonly known as vinyl weave.
  
−
The yarn is well twisted and spun of long staple wool (though nowadays also medium and short fibres are used). The wool is combed so that the fibres lie parallel.
+
<!--T:2-->
 +
[[Image:Plastic-canvas.jpg|thumb|right|100px|Plastic Canvas close-up]]
 +
* Plastic canvas is used as the base/foundation for needlepoint or other canvas work embroidery, usually in acrylic or wool knitting yarn. Because the plastic is rigid, it can be used in creating 3-dimensional projects like tissue box covers, small jewelry boxes, handbags, and other decorative items.
  
−
The cloth has a hard, smooth texture, usually whipcord, gabardine or serge, and the usual weave is a twill weave.
+
<!--T:3-->
 +
* Plastic canvas comes in many colors and various size holes for different thicknesses of yarn. As with textile canvas, these are described in count – 10-count plastic canvas has 10 holes per linear inch. Typical sizes are 7-, 10-, and 14 count. It also comes in pre-made shapes such as circles, triangles, as well as novelty shapes (e.g. dinosaurs, birds, etc.).
  
−
Worsted is also used for carpets, garments, hosiery and gloves.
+
<!--T:4-->
 +
* Plastic canvas is also used to teach needlepoint and cross stitch to children, because it is rigid and does not need the use of a hoop or frame.

<!-- 2. Name four types of plastic canvas and give a brief description of each. -->
 +
On the project pattern you will find that the plastic canvas grid is either counted out by using the terms ''lines'' or ''threads'' or by ''holes'' or ''squares''. You can find the following four sizes:
 +
* 5 holes to the inch
 +
* 7 holes to the inch
 +
* 10 holes to the inch
 +
* 14 holes to the inch
 +
 
 +
<!--T:6-->

Plastic canvas sheets are ''clear'' or ''colored'', ''stiff'' or ''soft'', which becomes the following four types:
 +
* clear & stiff
 +
* clear & soft

* colored & stiff
 +
* colored & soft
 +
 
 +
<!--T:31-->
 +
Stiff or even ultra stiff canvas is better for 3D projects you want to be free standing or that you want to stay flat. The soft canvas is better for projects like a bag or something you prefer to be more cloth like.

Worsted (pronounced '''woo''-stid), is the name of a yarn, the cloth made from this yarn, and a yarn weight category. The essential feature of a worsted yarn is straightness of fiber, in that the fibers lie parallel to each other.

The term "worsted" is often applied to any yarn spun from fibers three inches in length or longer that have been carded or combed, and spun, not just wool. Acrylic and other yarns can be called "worsted," as much a reference to the weight of the yarn as the production process.

{{AY Honors/Problematic requirement
 +
|the requirement calls for a "one-inch sample" which is inadequately small if interpreted as a straight line.
 +
|Name at least ten stitches and make a labeled sample sheet showing a one-inch square example of each field stitch, and a one inch long sample of the edge, fringe and panel joining stitches.
 +
}}
 +
This requirement is an excellent opportunity for the Pathfinders new to Plastic Canvas to learn and practice a variety of stitches and prepare the Pathfinders for the other practical projects in the honor. Other needlepoint type honors use similar stitches, so the skills are very transferable.
 +
 
 +
<!--T:40-->
 +
The requirement says "one-inch sample" which if interpreted as a single row is between 2 and 7 individual stitches in 7 point canvas. This is not an adequate number of stitches to learn any stitch and does not cover how to connect the rows of stitches side by side or how to transition to the next row. Instead, we interpret the requirement (and strongly recommend) that a sample '''1 inch by 1 inch square''' of each stitch (except as noted) be prepared by each Pathfinder in the form of a sample canvas. The finished sample canvas will give them a quick reference guide to keep with their plastic canvas kit. The one inch square or length is actually a good rule to enforce as it trains the Pathfinder to count stitches on the project, another important skill.
 +
 
 +
<!--T:41-->
 +
After some testing, we suggest this procedure:
 +
 
 +
<!--T:42-->
 +
#Prepare strips of 7 point canvas that are are ideally at least 12 inches long and 2 inches wide. We found canvas sheets that are a little larger then a letter size sheet of paper (10.5 inch/26.7 cm x 13.5 inch/34.2 cm) that can be cut the long way.
 +
#Each Pathfinder should create a sample canvas of a 1 inch square block of each of the listed stitches working to the edge of the canvas
 +
#Add samples of the edge stitches (where one inch samples will do).
 +
#Add labels (stickers or stitched) below each stitch sample.

<!--T:14-->

'''Tent stitch''' is a small, diagonal embroidery stitch that crosses over the intersection of one horizontal and one vertical thread of needlepoint canvas forming a slanted stitch at a 45 degree angle. It is also known as '''Petit point''' and '''Needlepoint stitch''' and is one of the most basic and versatile stitches used in needlepoint and other canvas work embroidery.
 +
 
 +
=== Tent stitch variants === <!--T:15-->
 +
There are three types of tent stitch, all producing the same appearance on the front of the canvas but each worked in a slightly different way and having particular characteristics, uses, benefits and drawbacks. These variants of tent stitch are known as '''basketweave''', '''continental''' and '''half cross''' tent stitches:
 +
 
 +
<!--T:16-->
 +
* '''Basketweave tent stitch'''<br />The basketweave form of tent stitch is worked in '''diagonal''' rows up and down the canvas. The yarn on the back of the canvas has a typical basketweave appearance, with alternating horizontal and vertical stitches. Basketweave is the best stitch to use for covering large areas of canvas as it does not distort the canvas as the other two forms of tent stitch do.
 +
 
 +
<!--T:74-->
 +
* '''Continental tent stitch'''<br />Continental stitch is worked from right to left across the canvas. It's primary use is for working a single row of stitching but may be worked in multiple rows if necessary. It can also be used for stitching vertical lines. It is normally used for working a single line or for filling very small areas because of the tendency of the stitch tension to pull and distort the canvas ground fabric out of shape. This method uses more yarn than half cross stitch tent stitch but is more hardwearing.
 +
 
 +
<!--T:17-->
 +
* '''Half cross tent stitch'''<br />Half cross stitch is worked from left to right across the canvas. As with Continental tent stitch it's primary use is for working a single row of stitching but may be worked in multiple rows if necessary. It can also be used for stitching vertical lines. It is normally used for working a single line or for filling very small areas because of the tendency of the stitch tension to pull and distort the canvas ground fabric out of shape. This method uses less yarn than other stitches but is not very durable as coverage on the back of the canvas is a little thin.
 +
 
 +
 
 +
===Bargello Technique=== <!--T:18-->
 +
[[W:Bargello|Bargello]] refers not just a stitching technique, but motifs created by the change of colors in the stitches. This section describes the vertical stitch and how it is combined with color and ‘stepping’ to create different motifs.
 +
 
 +
==== Examples ==== <!--T:19-->
 +

 +
Image:Flame.png|'''Flame stitch motif'''.<br />''Stitches step sharply across the design''.
 +
Image:DiamondBargello.png|'''Diamond motif'''.<br />''Stitches step sharply across the designs and color changes cause diamonds to appear''.
 +
 
 +
<!--T:20-->
 +
Image:MedalionWiki.png|'''Medallion design'''.<br />''Stitches are gradually stepped and color changes causes spheres or medallions to appear''.
 +
</gallery>
 +
 
 +
===Vertical Stitches=== <!--T:21-->
 +
Most agree that traditional Bargello pieces incorporate a series of all vertical stitches (vs. diagonal stitches). The basic unit is usually a vertical stitch of four threads, but other heights are possible.
 +
 
 +
<!--T:22-->
 +
Some Bargello pieces use only one height of stitch, but even the earliest pieces (such as chairs in the Bargello museum) combined different heights of stitches.
 +
 
 +
===Stepping=== <!--T:23-->
 +
Bargello patterns are formed when vertical stitches are '''stepped''' or offset vertically, usually by two threads (i.e. halfway down a unit of four threads). The patterns in the steps combined with color changes determines how the overall pattern will emerge.
 +
 +
===Flame (Sharp) vs. Curved Motifs===
 +
If vertical stitches are stepped down quickly, the design forms sharp points or zig-zags. This type of Bargello motif is often known as "flame stitch." Flame stitch can be found on the Bargello Museum chairs.
 +
 
 +
<!--T:24-->
 +
If steps are gradual, then the design will appear to be curved. Traditional curved Bargello motifs include medallions and ribbons.

These are all single or double sided, mostly one dimensional objects with a design of some sort. Any of these would make a good starter project. You can cut out of plastic mat or you can buy a precut kit, often in an interesting shape. Search online for stitching patterns, look in the library for pattern books or follow the directions that came with your kit. However, feel free to be creative and personalize your project with alternate colors or other modifications for after all it is your creation.

What is plastic canvas?


Train made in Plastic Canvas
  • Plastic canvas is a lightweight plastic material with regularly spaced holes in imitation of embroidery canvas. It is also commonly known as vinyl weave.
Plastic Canvas close-up
  • Plastic canvas is used as the base/foundation for needlepoint or other canvas work embroidery, usually in acrylic or wool knitting yarn. Because the plastic is rigid, it can be used in creating 3-dimensional projects like tissue box covers, small jewelry boxes, handbags, and other decorative items.
  • Plastic canvas comes in many colors and various size holes for different thicknesses of yarn. As with textile canvas, these are described in count – 10-count plastic canvas has 10 holes per linear inch. Typical sizes are 7-, 10-, and 14 count. It also comes in pre-made shapes such as circles, triangles, as well as novelty shapes (e.g. dinosaurs, birds, etc.).
  • Plastic canvas is also used to teach needlepoint and cross stitch to children, because it is rigid and does not need the use of a hoop or frame.


2

Name four types of plastic canvas and give a brief description of each.


On the project pattern you will find that the plastic canvas grid is either counted out by using the terms lines or threads or by holes or squares. You can find the following four sizes:

  • 5 holes to the inch
  • 7 holes to the inch
  • 10 holes to the inch
  • 14 holes to the inch

Plastic canvas sheets are clear or colored, stiff or soft, which becomes the following four types:

  • clear & stiff
  • clear & soft
  • colored & stiff
  • colored & soft

Stiff or even ultra stiff canvas is better for 3D projects you want to be free standing or that you want to stay flat. The soft canvas is better for projects like a bag or something you prefer to be more cloth like.


3

Which type of yarn is best for use on plastic canvas?


The best type of yarn to use is regular worsted weight yarn. It is inexpensive, comes in many colors, and is widely available.


4

Describe the following types of yarn and say on which type of canvas they work best:



4a

Worsted Weight Yarn


Worsted (pronounced 'woo-stid), is the name of a yarn, the cloth made from this yarn, and a yarn weight category. The essential feature of a worsted yarn is straightness of fiber, in that the fibers lie parallel to each other. Traditionally, long, fine staple wool was spun to create worsted yarn, but other long fibers are also used today.

The term "worsted" is often applied to any yarn spun from fibers three inches in length or longer that have been carded or combed, and spun, not just wool. Acrylic and other yarns can be called "worsted," as much a reference to the weight of the yarn as the production process.

It works well with #7 canvas, the most popular size.


4b

Sport Weight Yarn


Sport weight yarn is a bit lighter than worsted yarn, having 12 wraps per inch (wpi) compared to 9 wpi for worsted. It is good with higher count holes per inch canvas.


4c

Tapestry Yarn


Tapestry yarn or tapestry wool is a tightly twisted 4-ply yarn.


4d

Persian Wool


Persian yarn is a loosely twisted 3-strand yarn of wool or acrylic, often used for needlepoint.

This yarn will work well for #14 canvas.


4e

Pearl Cotton


Pearl cotton, Perle cotton, or French cotton perlé is an S-twisted, 2-ply thread with high sheen, sold in three sizes or weights (No. 3, 5, and 8, with 3 being the heaviest).


4f

Embroidery Floss


Embroidery floss or stranded cotton is a loosely twisted, slightly glossy 6-strand thread, usually of cotton but also manufactured in silk and rayon. Cotton floss is the standard thread for cross-stitch. Extremely shiny rayon floss is characteristic of Brazilian embroidery.

Use in 14 point canvas.



5

What type of needle is used on plastic canvas? Which size needle is used on each type of plastic canvas?


Various manufacturers make Metal Plastic Canvas Needles, also called tapestry needles. You need needles that have a large eye for the yarn and they do not need to be sharp. Most plastic canvas needles are quite short.

7pt plastic canvas takes a #16 metal tapestry needle. 10pt takes a #18 needle


6

Which instruments are used for cutting plastic canvas? How do you cut plastic canvas?


First you need a good cutting board (paper cutter), something most schools have, for the straight lines. A pair of sturdy scissors is useful for shorter segments and around circles.


7

Name at least ten (10) stitches and make a one-inch sample of each.


Note: The editors of this answer book feel that there is an error in the official version of this requirement.

the requirement calls for a "one-inch sample" which is inadequately small if interpreted as a straight line.

Proposed correction:
Name at least ten stitches and make a labeled sample sheet showing a one-inch square example of each field stitch, and a one inch long sample of the edge, fringe and panel joining stitches.

This requirement is an excellent opportunity for the Pathfinders new to Plastic Canvas to learn and practice a variety of stitches and prepare the Pathfinders for the other practical projects in the honor. Other needlepoint type honors use similar stitches, so the skills are very transferable.

The requirement says "one-inch sample" which if interpreted as a single row is between 2 and 7 individual stitches in 7 point canvas. This is not an adequate number of stitches to learn any stitch and does not cover how to connect the rows of stitches side by side or how to transition to the next row. Instead, we interpret the requirement (and strongly recommend) that a sample 1 inch by 1 inch square of each stitch (except as noted) be prepared by each Pathfinder in the form of a sample canvas. The finished sample canvas will give them a quick reference guide to keep with their plastic canvas kit. The one inch square or length is actually a good rule to enforce as it trains the Pathfinder to count stitches on the project, another important skill.

After some testing, we suggest this procedure:

  1. Prepare strips of 7 point canvas that are are ideally at least 12 inches long and 2 inches wide. We found canvas sheets that are a little larger then a letter size sheet of paper (10.5 inch/26.7 cm x 13.5 inch/34.2 cm) that can be cut the long way.
  2. Each Pathfinder should create a sample canvas of a 1 inch square block of each of the listed stitches working to the edge of the canvas
  3. Add samples of the edge stitches (where one inch samples will do).
  4. Add labels (stickers or stitched) below each stitch sample.

Tent Stitch

Basketweave tent stitch
Continental tent stitch
Half cross tent stitch

Tent stitch is a small, diagonal embroidery stitch that crosses over the intersection of one horizontal and one vertical thread of needlepoint canvas forming a slanted stitch at a 45 degree angle. It is also known as Petit point and Needlepoint stitch and is one of the most basic and versatile stitches used in needlepoint and other canvas work embroidery.

Tent stitch variants

There are three types of tent stitch, all producing the same appearance on the front of the canvas but each worked in a slightly different way and having particular characteristics, uses, benefits and drawbacks. These variants of tent stitch are known as basketweave, continental and half cross tent stitches:

  • Basketweave tent stitch
    The basketweave form of tent stitch is worked in diagonal rows up and down the canvas. The yarn on the back of the canvas has a typical basketweave appearance, with alternating horizontal and vertical stitches. Basketweave is the best stitch to use for covering large areas of canvas as it does not distort the canvas as the other two forms of tent stitch do.
  • Continental tent stitch
    Continental stitch is worked from right to left across the canvas. It's primary use is for working a single row of stitching but may be worked in multiple rows if necessary. It can also be used for stitching vertical lines. It is normally used for working a single line or for filling very small areas because of the tendency of the stitch tension to pull and distort the canvas ground fabric out of shape. This method uses more yarn than half cross stitch tent stitch but is more hardwearing.
  • Half cross tent stitch
    Half cross stitch is worked from left to right across the canvas. As with Continental tent stitch it's primary use is for working a single row of stitching but may be worked in multiple rows if necessary. It can also be used for stitching vertical lines. It is normally used for working a single line or for filling very small areas because of the tendency of the stitch tension to pull and distort the canvas ground fabric out of shape. This method uses less yarn than other stitches but is not very durable as coverage on the back of the canvas is a little thin.


Bargello Technique

Bargello refers not just a stitching technique, but motifs created by the change of colors in the stitches. This section describes the vertical stitch and how it is combined with color and ‘stepping’ to create different motifs.

Examples

  • Flame stitch motif.
    Stitches step sharply across the design.

  • Diamond motif.
    Stitches step sharply across the designs and color changes cause diamonds to appear.

  • Medallion design.
    Stitches are gradually stepped and color changes causes spheres or medallions to appear.

Vertical Stitches

Most agree that traditional Bargello pieces incorporate a series of all vertical stitches (vs. diagonal stitches). The basic unit is usually a vertical stitch of four threads, but other heights are possible.

Some Bargello pieces use only one height of stitch, but even the earliest pieces (such as chairs in the Bargello museum) combined different heights of stitches.

Stepping

Bargello patterns are formed when vertical stitches are stepped or offset vertically, usually by two threads (i.e. halfway down a unit of four threads). The patterns in the steps combined with color changes determines how the overall pattern will emerge.

Flame (Sharp) vs. Curved Motifs

If vertical stitches are stepped down quickly, the design forms sharp points or zig-zags. This type of Bargello motif is often known as "flame stitch." Flame stitch can be found on the Bargello Museum chairs.

If steps are gradual, then the design will appear to be curved. Traditional curved Bargello motifs include medallions and ribbons.

Make two of the following items using three different stitches.


These are all single or double sided, mostly one dimensional objects with a design of some sort. Any of these would make a good starter project. You can cut out of plastic mat or you can buy a precut kit, often in an interesting shape. Search online for stitching patterns, look in the library for pattern books or follow the directions that came with your kit. However, feel free to be creative and personalize your project with alternate colors or other modifications for after all it is your creation.

Make one of the following using four different stitches:


These are all three dimensional boxes of some sort. They allow the Pathfinder to learn to attach panels together and explore three dimensions.


9a

Tissue Box Cover


This project is a simple four sided box, with a top with a hole for tissues and the bottom open. The sides and top represent places for the Pathfinder to follow interesting patterns or create their own design on.


9b

Tote Bag


This should have a bottom and sides, basically the same as a box with some handles cut in the sides. Totebag kits can be purchased or follow a pattern.


9c

Floppy Disk Holder


Most Pathfinders will not know what a floppy disk is, and sure do not need one for they were born well after floppy disks became obsolete. Floppies were removable computer storage media. A similar, and not quite obsolete item might be a business card holder or a small box to store store loyalty cards in. Basically a little box to put something rectangular in.


9d

Trinket/Coaster Box


A box with a bottom, and perhaps a lid. Again, a three dimensional box.
