This is the “filled in” version of the original granny square baby blanket which is very lacy. I love this pattern because the result is a nice warm blanket with a beautiful mitered look. The pattern is also great for beginners because it is so easy that you can have it memorized by the end of this tutorial. To achieve the striped look in the blankets above, you will just need to follow this tutorial and change thread colors every two rounds. For the blankets above and in this tutorial, I used a US size G crochet hook with cotton sport weight yarn, but you can use just about any hook/yarn combination that you like. Here we go!
