free pattern, tumblr didn’t want me to share the original with you the original for some reason.
You can find it at Crochet Me. (The soles are built on flip-flops!)
EDIT: It has been pointed out to me that I was mistaken about the pattern being free. It is actually part of a digital magazine download for $6.99. The free part shows the technical info & how they made the sole, but that’s it. Sorry for the error! I was too excited about the flip-flop sole & didn’t look passed the pictures.
