Here is a really good idea for your toenails!
Buy a regular toenail polish that you like( I would recomend a brighter color nothing like brown, tan, or light blue).Next buy a bottle of black, white, and sparkly, nail polish with a very small brush on the end (you can find these at Walgreens).
Put at least 3 layers of nail polish if you want it to stay on longer, and after that put on a a layer of clear (if you don't have any clear thats okay).
let that dry and then you can do any design you want!
This is so cool that I've even had someone ask me if I had a Pedicure!
