This is growing to be one of our very favorite baby afghan patterns! An easy to follow stitch pattern, knits up the cutest hearts. We find that in a blue or green color, this is well suited for boy babies too. We started with the doll size blanket, and then we added directions for a baby blanket. Doll blanket is a good size for preemie babies at 17 b y 18 ½. Baby blanket is about 38 by 40. Uses worsted weight yarns, knitting needles, size 10.5.
