I have crocheted a baby afghan in the pattern commonly called granny stripes. I have seen it many places around the internet, so I don't have a particular pattern link. I used a baby yarn from "Big Lots" that is labeled as Hand Knitting Yarn For Baby Projects. I chained the length I wanted, using a G hook, and then crocheted a 3 dc shell in every other stitch. The next row was a 3 dc shell in the place between the shells, just like in a granny square. I chose to have three rows of each color, with 12 rows of white between them. I edged the blanket with a row of sc, followed by a row of sc, ch 3, sc.
