Have found Madeira threads (used in embroidery) in variegated colors, similar to the Gudebrod threads used to wrap the old blanks. Comes in 9 colors, but before I go invest in it, I'd like some input. Have you used it? Does it really compare? Will it hold up? Does it take to the finish? It's 40 wt, made of rayon. Really kewl colors, too!!
