I found this question harder than the mainstream one a few weeks ago. I could have chosen more however AJ Nails Collection, Prism Polish, Danglefoot, Fancy Gloss and Tonic have to be up there in my top five indie brands.
I don't have a great deal of shimmer polishes, that said Polish Me Silly Candy Glow and Leighton Denny Diamond Rose are two favourites. Candy Glow turns black polish a shimmer blue and Diamond Rose turns black a rose shimmer.
