This is a great little project that I plan to do again one day. It's a rag rug that I made using a big ol' crochet hook and some strips of fabric. You just cut long strips out of whatever fabric you want and connect them together by cutting a slit in each end so you can make a slipknot. Treat it like yarn and crochet whatever shape rug you want with the fattest hook you can find. I just made a chain and crocheted row after row of single crochet stitches til it was the size I wanted. I then worked around the edges to give it a finished look.
My hands KILLED as I did this... I think it was because my fabric was heavier AND I cut my strips too wide for the hook I had. Do what feels good to you. It shouldn't hurt your hands like it did for me :) I'd love to see yours!
