Starting out a guy needs everything going in his direction and using proven products will help in that regard. Once you're getting a feel for this stuff you can poke around in after-market things but you're far better off using reputable products. You'll find such at Do-It. I mix Do-It .015 green, blue, copper and purple glitter together in equal portions to make what I call my bluegill blend. I use a half-pint canning jar/lid and simply dump one container of each color in it and mix it up with the cap on. I use this blend in clear plastic and its beautiful. I found some glitter at a Hobby Lobby that had all four of these colors and 8 others in a "set" and bought one thinking it was cheaper. I did the mix per usual. A few days later I grabbed the jar of el jappo cheapo stuff and just as I addedit to my batch of plastic I noticed that the whole jar had changed color. Too late for the batch but I coked it up anyway. At about 290 degrees I was looking at a big ugly wad of plastic that wasn't really orange but not quite brown either but was full of silver glitter. The stuff bled dry in the jar and with heat the color washed right off the underlying silver mylar.
I know its tempting to hit those craft shops for some of this stuff but give yourself a chance to get acquainted with the plastic before you start going to the cheap.
