For each contrast color, I carried the yarn up along the side by knitting the second stitch with both the contrast color and the main color, on the right side only. I didn't carry the main color through the color blocks in section 1, but I'm going to do that in section 4, just to have less ends to weave in. Whenever joining a new contrast color I attached it to the main color with a square knot, and then wove the tail back into itself - sewing it through the main strand of the contrast color with a darning needle using a running stitch - to anchor it, that way I only have a single end to weave in for each color.
