This one is simple and a half! All you do is paint a base coat, then take two pieces of tape, use the corners, and stack like them like pictured and then paint as you please in the opening of the tape.
-Wait until your base coat is COMPLETELY dry.. or you will pull off the polish with the tape.
-Stick the tape to your skin and pull off, repeat a few more times. Do this so you remove the 100% stickiness of the tape.
-Be picky about the edge of the tape and make sure there is a good "seal" on it. No air bubbles, lifting, etc.
Then finish with a top coat!
