I have made a fluid bed for my jig painting. I am now shopping for powder. Any suggestions on places to acquire it? I will really only be trying to paint black, brown, purple, blue, pumpkin and green pumpkin. Can I create some of these colors by mixing 2 colors? I made 2 paint cups with coffee filters and I have a couple more to make with a different material. any suggestion on another material to use? I'll post a pic later tonight when I have more time.
