I'm no hand knitter, but I wanted to try knitting a seamless sweater in the round. There is a good tutorial available at Knitpicks.com, complete with videos and handouts. I used bulky yarn because I can't tolerate the snail's pace that smaller yarns knit at. It went very quickly, about two weeks, and I didn't make all that many mistakes. Knitting round means no purling which speeds things up exponentially. I made some miscalculations about the amount of curl at the hem, but otherwise it turned out quite well. The yarn is Wool of the Andes bulky in redwood, which was being discontinued when I purchased it.
I really like the appearance of raglan seams by strategically placing the decreases. This project was a lot of fun and I would do it again (with bulky yarn).
