My friends call me the "YO-YO Queen". I've made thousands of yos into a queen sized quilt (no backing used),
a vest, ornaments, napkin rings, Christmas tree wall hanging, dresser runner, pillows, candle mats and decorative additions to other items. They are great to make while traveling, waiting for appointments or watching TV. Sorry about your granddaughter, wishing her all the best.
Now go and make something wonderful with your yos.
