I love that pattern. It is such a quick knit and so easy to make. Plus, cheap- I use Peaches and Cream and buy calico fabric and ribbon at Hobby Lobby for next to nothing. I have already made four of them, and I have 3 friends that are expecting twins. So I guess, if they all have girls, I'll be making 6 more of them.
Yours looks great! Love the idea of making the slippers to go with them.
