The Whip Stitch is also known as the "Overcast Stitch," as each stitch of thread wraps around the edge of the fabric. It is a simple stitch for children to learn when sewing together two pieces of felt, where their sewing will be visible on the top side of their work (as opposed to stitching a seam with fabric right sides together and then turning it right-side-out, hiding the seam). You'll encounter it in many Level I felt kits, such as the Valentine Cookies. It's also an easy alternative anytime a Blanket Stitch is suggested.
Please note that this "Stitch Guide" is a work in progress. We'll have new illustrations and a few helpful videos soon!
Start with your needle in between the two layers of fabric and poke it up through the top layer, about 1/4” (or desired seam allowance) from the upper left edge. This will hide your knot in between the layers.
If your Whip Stitch is going to be part of a stuffed seam, you'll want to make sure that your knot doesn't pull through the felt under tension. As an extra security, make a first stitch in place by wrapping your thread over the top edge of both fabrics and poking your needle through both layers from back to front in the same place.
A first secure stitch in place
Repeat your first stitch, but this time, exit your needle about 1/8-1/4” to the right of your starting place. Continue working left to right (or right to left), always inserting your needle from back to front and moving about 1/4” away from your previous stitch.
Hiding Your Knot:
Reinforce your last stitch with an overlapping stitch, inserting your needle from back to front through the same place. Tie a double knot in your thread right against the fabric. Insert your needle next to this knot and exit it elsewhere, at least 1 inch away. Pull the thread tight until you feel your knot pop into the felt. Trim the extra thread off flush with the fabric. Your knot will be hidden!
