Heres what i did...First i bought two, cheap, different colored, size large crew neck sweatershirts. One black, one purple. Then i cut one somewhere around the middle at an angle all the way around. And i did the same with the other, except theres a bit of simple addition to do. Lets say they are each 28 inches long, and i want the end result at a length of 36 inches. So i made each section about 18 inches long or so, measuring from the top on the purple and the bottom on the black. Then i sewed them together!
