I actually bought pounds of glitter, but don't use is all that much. I mean sometimes I get ask for glitter, but not as mush as I thought it would be. Bet I have 6 or more different colors and a pound of each that I bought from CSI (Pro-Tech). I will end up selling a good bit of it on ebay since I don't think I will ever use that much. Guys use all kind like Fatman said and I even had some I bought from craft stores, but in the end I wanted what CSI had as well as their colors. I buy paint the same way.
I am with Fatman about using much make the head rough as heck, which I have seen some heads like that and didn't care for them enough to try them and they still sit in my tying room, but that is just me.
