I was hit by another flash of inspiration when i entered a little cafe today. i really liked the tiles in the cafe and decided i would try to make some kind of nail art. Since i don't have more nail strips laying around my house i decided to make my own with tape, I didn't use tape but instead post it flags, since i find them easier to paint on. And if you don't want any mess painting on a paper underneath will be the easiest way. You can paint with any kind of color you know will stay put even after applying a top coat, i used nail polish to paint with.
Tip: Using post it flags is probably the best idea, since they don't stick to the paper. Cutting the post it flags when they are still on the paper makes it a lot easier to cut and gives you more control. Since it's post it flags it's easy to remove from the paper and apply on the nail.
