I made this primarily because I really like chevrons and I wanted to get some practice with color changing. I'm not completely thrilled with how it came out, but I think i'll make more and see if I can improve on my technique. I tried several ways to change color and found a neat one that takes care of weaving in ends by crocheting over them.
