I recently purchased this book at ACMoore and it has so many WONDERFUL easy patterns for knitting children's sweaters. This is the BEST one I've purchased yet. They are easy patterns but still very stylish.
See the book here..
I purchased that book last Fall, and I agree, the patterns are nice. I knit up one of the vests for a Christmas present in KnitPicks Swish superwash and it came out lovely. (I don't have a photo, sorry - still waiting on the mom to take one!)
