hi i have read a lot about mixing but when i tried it wasnt that good. I havent any thing to mix with but have found a small icecream spoon. I was going to mix flawless pink and perfect pink together but dont know how much. Ive read somewhere 50/50. But how much scoops is that each. Do you just do enough for a set? Will i fill the whole icecream spoon up with powder too?
