The blanket is made with tapestry crochet technique. When you change color, finish the double crochet yarning over the new color. As you continue your project carry the baby green yarn by crocheting around it. For the other 3 colors work by square, leave the yarn as you change color, use Bobby pin to keep your yarn from unrolling and entangling . You can make 4 squares with each softly baby ice yarn.
