Last night my husband used our ball of string to tie up our cardboard boxes for recycling. When he was done, he left it sitting near my knitting spot. As I was looking at it, it occurred to me that it might make interesting crocheted coasters. So, I gave it a try. This is what I came up with:
I used string from the hardware store and a size J crochet hook. It is just single crochet, and I did a 12 stitch by 12 row square. I like them!
