Just wondering if anyone remembers the discontinued Gudebrod Color System designed a few decades ago by Gary Borger? I still use the plastic Gudebrod thread holders for most of the large saltwater flies I tie and wonder if anyone might have some thread holders they would sell me or know of anyone who might have a few they might want to get rid of? (They hold long thread spools, and I use a lot of Sulky polyester thread on long spools for saltwater tying.)
