1. Thread a needle with matching or neutral thread and tie a knot about 6" from end. With an assorted green print or polka dot A circle facedown, turn raw edge of circle a scant 1⁄4" toward circle center. Take small, evenly spaced running stitches near the folded edge to secure it.
2. End stitching next to starting point. Do not cut thread. Gently pull thread ends to gather folded edge until it forms a small gathered circle. Knot and trim thread to make an A yo-yo.
3. Repeat steps 1 and 2 to make nine A yo-yos total, 18 B yo-yos, 9 C yo-yos, 16 D yo-yos, and 19 E yo-yos.
