I recently posted that I had purchased some striping polishes from Sally Beauty Supply.
I think they were about $4 each. I really wish I would have gotten a black too - oh don't worry, one day I will! :-P
I was messing around with them the other night, so here's what I did!
If you have any pictures of your nails (or someone else's nails) with striping polish, feel free to link (or picture) in the comments! I'd love to get some good ideas!
