What You Need:
Paint base coat.
Let dry, all the way.
For reals, this is important.
Watch a movie or somethin', like the Prestige.
Dip finger into rubbing alcohol for about 5 sec.
Take out, put newspaper on nail.
Hold on nail for 2-5 sec.
Drop some more rubbing alcohol on top so it comes off easily.
Put on your top coat.
Let dry.. duh.
I did this with my friends, it was cute.
Also, make sure it is smearable ink, or else you'll have problems.
It won't come off onto your nail very well.
