This design was good fun and easy to do. I started with a silver base, and the added some glitter. I used two different silver glitters. Cosmic Girl from Danglefoot Polish gave a lovely twinkly and somewhat holographic look, and then I added some Diamond Glitter from Barry M for some larger glitter pieces and extra sparkle.
I googled Unicorn Oil Slick and came across a handy video from Nails by Jema. I enjoyed watching the video for tips. I knew how I was going to do the nails but wanted to check out my options! I decided to change my original plan of smooshing the colours onto my nails with a stamper, and followed Jema's advice of using my Uber Mat to create decals instead. This meant I could create more than I needed, and select only the best ones to use. I'm glad I did that as some of the ones on my mat weren't as good as I'd have liked. The ones on my nails were the most multi coloured, still ended up with one very pink little finger though!
