I wound three warps with different fibers. Using 16/2 rayon I will use the Peacock Twill draft. With 10/2 Tencel I will do the V for Virginia draft, and 2/8 Bamboo for the Northern Lights draft. All three of these drafts will work great with a painted warp.
correction: the rayon is 12/2 ..updated 5/31/2012
