Dubbung is a learned skill, the more you do it, the better you get. Almost everyone uses too much dubbing to start with. You want to just coat the thread very thinly and evenly, kinda like core spinning angora or whool for knitting and weaving. Get some dubbing wax, it helps. Keep working on one or two patterns until they come out looking like the book shots or as close as you can get. Don't get frustrated, it doesn't help in the end, just walk away from it for a while. The longer you tie, the more goodies you'll pick up. If you'd like to try a Renzetti rotary vice, let me know, I'm off Sunday and can give you or anyone directions to my place to sit and tie for a while.
