One year I also knitted tiny sweater ornaments for my coworkers (knit in the round on sock needles). I also did a stocking. They took about an hour apiece to make, I think, and I really did it more for the challenge of figuring out how to do it than anything else.
There are patterns for similar little sweater ornaments online, but at that time there weren't any knit in the round like I wanted. There may be now, that was several years ago.
