If you can't find/don't have a color of dubbing you need, it is pretty easy and dirt cheap to make your own dubbing. Toss some chopped up yarn pieces (less than 1"), some ice dub/polar flash, and some rabbit guard hairs or squirrel tail into a coffee grinder and you have a great dubbing for just pennies. You can make any color just by mixing a few colors of yarn. Just don't use that coffee grinder for coffee again unless you want a mustache...
