I think I have reached the stage in my tying apprenticeship where I need to find an effective way to mix dub. What I normally do is pick a bit of this, a bit of that and maybe some of another, roll into a ball and pull apart. The process is repeated for as long as I can be bothered usually.
I seem to rem reading ages ago about using hand operated coffee grinders and something else about an airline and a plazi bag

.
My current method works ok but I would like to produce a small bag full so that next time I tie, the fly comes out the same.
Any advice would be much appreciated.
Chris.
