This pattern uses three stitches (knit, purl, and yarn over) to make two triangles which are then sewn together, about halfway up. This shawl really doesn’t take much yarn, I used scraps for the entire project. Four colors are used, almost equal amounts of colors A and B, but colors B and C are only used for the beginning and penultimate stripes. For me, Color A was the darkest blue, Color B was the medium blue, Color C was white, and Color D was the light blue.
