• 

  Thimble

• Tape measure sewing.png

  Tape Measure

• 

  Scissors

• 

  Pinking Shears

• 

  Needles

a. Thimble

A thimble is a protective shield worn on the finger or thumb. A thimble is most usually made from metal, leather, rubber, wood, glass or china.

d. Pinking shears

Pinking shears are scissors whose blades are sawtooth instead of straight. Pinking shears will leave a zigzag pattern instead of a straight edge.

Pinking shears are useful for cutting woven cloth. Cloth edges that are unfinished will easily fray, the weave becoming undone and threads pull out easily. The sawtooth pattern does not prevent the fraying but limits the length of the frayed thread and thus limits damage.

2. Become acquainted with the sewing machine in your home or school. Identify:

a. Balance wheel

1: Balance Wheel; 2: Backspace lever

The balance wheel provides a method of manually moving the the needle up or down. It is used to raise the needle out of the cloth when s stitch is finished, or to raise the thread take-up to make it accessible when threading the machine.

b. Thread take-up

Thread take-up

The thread take-up moves up and down with the needle, keeping the thread tight and drawing it from the spool as needed.

c. Presser foot

The presser foot holds the cloth in place while the needle runs thread through it. See the photo below for its location.

d. Presser foot lifter

Presser foot lifter

The presser foot lifter raises and lowers the presser foot. Raise it when you need to place a piece of cloth under the needle (and under the presser foot).

e. Needle

1) Needle, 2) Presser foot, 3) Feed dogs

The needle stitches the thread (green in the photo) through the cloth.

f. Feed dogs

The feed dogs are little tread-like pieces beneath the presser foot. As the sewing machine is operated, the feed dogs advance the cloth forward (or backwards if the backspace lever is activated). The presser foot holds the cloth against the feed dogs so that they can move the cloth along.

4. Put a hem in one of the following items showing neat and even stitches.

• a. Towel
• b. Apron
• c. Flannel baby blanket
• d. Flannel lap blanket
