Welcome to our article to make a free crochet blanket patterns that looks like rainbow colors. We will do it in a way that the color transitions of the free crochet blanket will be slow. We will get help from color tones for this process. First, create a template on paper. The template will be your guide for colors. Start creating the squares based on the length and width. It has some resemblance to the granny stitch method. After the blanket interior is complete, let’s complete the finishing edges. We will use different colors of yarn in each row on the edges. The edges can be any width you want. It will be more spectacular if you crochet patterns free from all the colors used in the interior. All children will love this blanket.
