Crochet 10 rows and make sure your squares are as close to perfect as possible. If not, you may adjust the number of rows before you switch to a new color combination. For my crochet baby blanket pattern, 10 rows were perfect. As you can see, it is a very easy crochet blanket stitch: you are alternating two basic crochet stitches – SC and HDC. But as a result, you have an interesting textured blanket that has a warm and dense fabric structure.
