Made by the super-fab Nikki, who says:
Now, let me suggest that knit thongs be the new socks. Portable, fun and interesting construction, no seaming, and talk about quick. There’s not much to a thong, people. Go ahead and try yours in a heavy machine washable sock yarn if you must, but you must try. Won’t take you more than an evening, I guarantee. Pattern at Interweave Knits.
