I promised a few weeks ago to share this pattern, and finally had a bit of time to find it and fix it up for you! These slippers are knit flat and seamed up the back, and shaped to fit the toys with rounded feet (not the toys with big feet like the bunnies and monkeys). I don't remember how much yarn I used to knit these, but it wasn't very much. If you try out the pattern, maybe you could leave a comment telling others how much yarn you needed.
