This top is made in 2 pieces from the bottom up. The sleeves are added using a cable cast on.
Small and Med. Will need 1 skein of each color.
Lg. I was able to make the large with only one of each with very little left over and reused my swatch.
Xlg, 2xl, 3xl require 2 of each color or 3 skeins total if you plan on making the top solid.
