Thread a needle with matching or neutral thread and tie a knot about 6" from end. With an assorted print circle facedown, turn raw edge of circle a scant 1/4" toward circle center. Take small, evenly spaced running stitches (Running Stitch Diagram) near folded edge (Photo 1). To make a running stitch, pull the needle up at A and insert it back into the fabric at B, 1/8" away from A. Pull your needle up at C, 1/8" away from B. End stitching next to the starting point; do not cut thread. Gently pull thread ends to gather folded edge until it forms a gathered circle (Photo 2).
Knot thread ends to make a yo-yo. Trim thread. Repeat to make 130 yo-yos total.
