I finally got the hang of using Nail Vinyls! I took the advice of my lovely readers, and as much as I didn't want to add extra layers, I used a layer of fast-drying topcoat before applying the Vinyls.
For this look I started with a base of OPI My Vampire is Buff. Then applied Seche Vite, and a thick chevron nail vinyl. From there I painted the two purple shades: OPI Miss You-niverse and Essie Play Date. Removed the nail vinyls, top coated the whole look and voila!
Of course now that I've gotten the hand of using them, I've been using them all the time! Hope you guys like this look :)
