Template:Otheruses Template:Unreferenced A zigzag is a pattern made up of small corners at variable angles, though constant within the zigzag, tracing a path between two parallel lines; it can be described as both jagged and fairly regular. Traditionally a "zig" points in the left direction (/) and a "zag" points right (\). From the point of view of symmetry, a regular zigzag can be generated from a simple motif like a line segment by repeated application of a glide reflection. Equally it is the juxtaposition of chevrons, or of forward slashes and backslashes:

Lightning is often drawn as a zigzag, with long downward strokes and short backward ones. Stores of the defunct U.S. retail chain The Treasury (also Treasure Island) each had a distinct zigzag roof, many of which still survive on reused buildings nearly three decades after the chain closed. The roof zigzag was also seen on the store logo.

An automobile can move in a zigzag, that is, not going straight, but instead turning left and right and left repeatedly. In a city where streets are oriented toward the four cardinal directions, this would be illustrated by, for example, driving north, west, north, west, north, west, and so on around the city blocks, in order to go northwest. (This would not make the trip any shorter; however, it might avoid traffic.)

The trace of a triangle wave or a sawtooth wave is a zigzag. Pinking shears are designed to cut cloth or paper with a zigzag edge, to lessen fraying. Zigzags are a basic decorative pattern used on pottery, and often for the cuts which separate ravioli.

In sewing, a zigzag stitch is a machine stitch in a zigzag pattern. Tightly spaced zigzag stitches are used to emulate embroidery stitches such as satin stitch, and to reinforce buttonholes. A zigzag stitch is also used as a non-structural seam, to temporarily hold two panels together edge-to-edge (and eliminate the ridge that would "x-ray" through). This is done when another panel will overlay the seam and provide support.

+A '''zigzag''' is a [[pattern]] made up of small corners at variable angles, though constant within the zigzag, tracing a path between two [[parallel lines]]; it can be described as both jagged and fairly regular.
+Traditionally a "zig" points in the left direction (/) and a "zag" points right (\).
+From the point of view of [[symmetry]], a regular zigzag can be generated from a simple motif like a [[line segment]] by repeated application of a [[glide reflection]]. Equally it is the [[juxtaposition]] of [[chevron (insignia)|chevron]]s, or of [[forward slash]]es and [[backslash]]es:

-These are all items you can buy in a department store or even in a thrift shop.  It is also possible that you have an older relative who no longer sews and would ''love'' to give your some sewing supplies, especially if you show a real interest in learning the craft.  Don't feel as though you need to buy everything on the list right away.  You can spread out your acquisitions over time as you hunt for bargains.

-In sewing, to '''baste''' or '''tack''' is to make quick, temporary stitching intended to be removed.  Tacking is used in a variety of ways:
-* To temporarily hold a seam or trim in place until it can be permanently sewn, usually with a long running stitch made by hand or machine called a '''tacking stitch''' or '''basting stitch'''.
+The [[trace]] of a [[triangle wave]] or a [[sawtooth wave]] is a zigzag. [[Pinking shears]] are designed to cut cloth or paper with a zigzag edge, to lessen fraying. Zigzags are a basic decorative pattern used on [[pottery]], and often for the cuts which separate [[ravioli]].
-* To temporarily attach a lace collar, ruffles, or other trim to clothing so that the attached article may be removed easily for cleaning or to be worn with a different garment.  For this purpose, tacking stitches are sewn by hand in such a way that they are almost invisible from the outside of the garment.
+In [[sewing]], a '''zigzag stitch''' is a [[sewing machine|machine]] stitch in a zigzag pattern.  Tightly spaced zigzag stitches are used to emulate [[embroidery stitch]]es such as satin stitch, and to reinforce [[buttonhole]]s.
+A zigzag stitch is also used as a non-structural seam, to temporarily hold two panels together edge-to-edge (and eliminate the ridge that would "x-ray" through).  This is done when another panel will overlay the seam and provide support.
-* To transfer pattern markings to fabric, or to otherwise mark the point where two pieces of fabric are to be joined.  A special loose looped stitch used for this purpose is called a '''tack''' or '''tailor's tack'''.

-* A basting stitch is essentially a straight stitch, sewn with long stitches and unfinished ends.  The basting stitch is used for temporarily holding sandwiched pieces of fabric in place.  The stitch is removed after the piece is finished.  Often used in quilting or embroidery.
