Lee; I've used it for dubbing, and I have also dyed some of the lighter stuff in Kool-Aid to get some purples and oranges, for streamers. I live on the world-famous Thompson River- I should be out there with my spey rod swinging for steel, but I'm still trying to get me mule deer!
I'm working on a plank maple molle right now, and some of the grain on the back is 'iffy'. Just wondered about an alternative, just for the sake of being different. I can't find flax around here, may need toorder some.
