Thanks! You know what, I'm not sure how it compares to socks, because like ArtLady, I've never knitted a sock and really have no desire to. I can see me knitting some slippers at some point though. I used a "basic mitten" pattern - nothing fancy. So no, it wasn't that difficult. You should give them a try!
Finished the other mitten, btw. Can't wait to give them a test run tomorrow when I go out shopping!
