One more question, if I want to mix 2 colors to make a total new color, should I do that in a small container and then add it? I am thinking getting 3 primary colors gives me a lot of colors I can mix myself, of course getting black and white along with the 3 others.

For my first plastic order, it will likely be the one I have found a couple places with very little odor and a medium strength. Unless someone has a better idea. I don't know if I will be getting any strengtheners or other stuff right off the bat. Just basics so I am learning right and not messing with too much stuff confusing myself.
