Alrighty, you asked and I shall deliver! I've had a lot of people asking me how I do my Glitter Mosaic nails so I took some time last night to full document how to do it. Be warned, there are a TON of pictures and even a time lapse video to follow. Step 1. Gather your supplies. I'm using Essie Ridge Filler as a base coat, Rimmel Black Satin as my base colour, a pot of hexagonal gold glitter from ebay for the glitter and a toothpick. Step 2. Add your base coat and two coats of your base colour.
