I just finished up a child sized one. The hardest part is starting out with eight sts on four needles, but once you get passed that.... It's really easy. I did the sleeve differently, using the "afterthought heel" technique which was, IMHO, much easier than the convulted instructions for a provisional CO!
Lizzie, that turned out cute. I'd like to make one for myself and granddaughter too. She'll soon be three. I haven't read all of the instructions yet. How many buttons are on the front or is it held together another way?
