Okay, just when I think I am all set I find a new direction for this hobby (obsession) of fly tying. My latest is dying materials. I was working on a pattern that called for green hackle. No problem I thought, lots of people use kool aid so I will learn that, but none of our local stores carry lemon lime which is the green for most of the combinations. I started looking around and found an article saying to never use kool aid or Rit, so no problem, I will use what they recommend. One suggestion was Veniards, but I could not find any sources in the US. They also suggest Jacquard which I can probably find at Joann's. Short of using a magic marker, what do the rest of you use? And more important, where do you get it?
