What is a whipstitch?

A whipstitch is simply a stitch that passes over the edge of the fabric and it is done by hand.

Begin the whipstitch by tying a knot in the end of the thread.

Then poke the needle through the top layer of fabric, about 1/8" in

Then go over the edge of the fabric and poke the needle up through both layers of fabric about 1/8" from the edge.  The distance between the stitches can vary depending on how you'd like the stitch to look.  Generally, about 3/4" or a tab wider is good.

Repeat till you get to the end of the fabric you are stitching.

Tie a knot to secure.

When whipsitching, you want to use a fabric type that won't fray around the edges.

Felt fabric is best not only because it doesn't fray but because it doesn't have a lot of pull.  So the stitch looks good.  Felt however is very limited in colors and patterns.

Fleece fabric also can be used because it doesn't fray around the edges but it very soft and flexible.  The stitch still looks good but you just have to remember not to pull the stitch too hard.  Let it sit on the edge and don't pull it any further.  Fleece is available in many colors and patterns at most fabric stores.
