To create the abstract manicure pictured, I applied a base coat followed by two coats of CND Shellac polish in Cream Puff (although normal nail polish will also work great if you don't have a gel system at home). I finished with a supershiny topcoat.
When the topcoat is fully dry, this is where the magic happens — and where it gets a little finicky. Decide which stickers you want and carefully cut each design out from the sheet (as you can see I did from the picture in the previous slide). This will make it easier to peel off.
When you're happy with your chosen stickers, take a pair of tweezers and peel the sticker off from the sheet and place it onto your nail. After you've placed it down, carefully press it (using tweezers or your fingertip) to make sure it's fully stuck onto your nail. Take extra care to make sure there are no air bubbles or lifted edges, which will make it easier for the stickers to start peeling off, thus shortening the wear time.
Once all of the stickers are in place, add another layer of clear topcoat to seal it all in and make the edges of the stickers look seamless. When the final topcoat is dry, all that's left to do is snap a nail pic and marvel at your excellent work.
