Fits women's foot length of 8, 9, or 10 inches. Fun, fast to make. Reminiscent of our younger days of wearing "Mary Jane" type shoes! These work up fast, so you can make several pairs each, for all your friends too! Uses up scraps of yarn, and knitting needles, US #10. A decorative optional button can be used for decorative purposes on strap. Fit well, and wear well!
