The baby blanket I knit for pregnant friend number 2 is probably my favorite project that I've knit so far - but the stiffness of the cotton yarn did a number on my tendinitis, so I'd never attempt it again. Well, at least not in that yarn.
It took me 5-6 weeks to knit. The yarn is three strands of 3/2 mercerized cotton. I switched out one strand more than once for the color striping. I pieced the pattern together - a 2" garter stitch border, my beloved leaf vine pattern (from Barbara G. Walker's Second Treasury of Knitting Patterns), and the rest is stockinette. I cast on 100 stitches, which wasn't enough for the yard width I was going for - it's close to 24 inches, not 36. Still, I'm pretty damn happy with it.
There are two more pics on my Flickr. I love the leaf vine pattern, and do intend to make some blanket squares in it at some point.
