I can do my best! I can do those color combos, and see what I can come up with! I have red, yellow, green and blue, ruby, jet black and jade fritt and turbo cobalt powder. I haven't used powders yet so I don't know how much different they are than fritt. I ordered a Northstar sample pack so I have every color. It's nice having a reason to try more of them, see how they work and how the color comes out. It will help me know which colors I like, how easily they work and which ones I want to order more of!
