It is a toe-up, short-row heel sock done on two circular needles by Cat Borhdi
I just blindly followed the pattern and it was interesting to see how the heel progressed! I haven't ever done short rows or the figure 8 cast on, so this was a totally new experience for me.
Okay, so it is a miniature sock, but still, my first sock!
I made it for a bookmark. The pattern had a sock on both ends, but I opted to have just one.
