I bought the prepack kit, not too keen on the white, have only tested that & the blue one. I also have the shellac 3.0 collection & some separate shellac colours I bought before, longing lilac, tutti fruiti, the brown, white, red & negliee. Think that's all. What awesome effect can get from these additives, I blended the white & tutti shellac, & blue additive with the tutti fruiti too. I would like to use what I have, but I'm shady on the whole colour/ layering, I want to get full use out of the additives, any photos you have taken? . Would like to pick brains with ideas to get out there.
