Step 03
Fold under a scant 1/4" along the edge of your circle, as you stitch close to the folded edge. Use strong thread and make sure it's long enough to go around the full circumference of the circle, with some to spare.
Note: Shorter stitches create a larger, more open center on your yo-yo (see Step 04). Longer stitches make for a tighter yo-yo center (see Steps 05 & 06).
