My sister really liked the flip-flop socks but wanted a pair for her hands. So I made a couple of alterations to the pattern and got the results shown. Instead of casting on 34 stitches, I did 36. After setting aside the 12 stitches for the toe (thumb), I knit 5 more rows before doing the ribbing at the top. And I used size 4 dpns so the finished product was a little looser and softer.
