This weekend I managed to try something I've been wanting to do for quite a while: Crystallized Nail Art! I followed the steps from this tutorial and I'm quite happy with the result...
The only tips I can give you are:
a. use pastel colors or bright ones since the salt becomes white after it dries (no matter how many layers of top coat you use)
b. don't lick your nails... they're really salty :P
The light wasn't good when I took the pictures so the dark pink I used (somewhat fuchsia) turned into a shade of red in the pictures. ( Yes, I know, my nails resemble the American flag :P )
