Hi everyone,
This one is EXTREMELY simple. It does take patience though. Make sure your base colour is ABSOLUTELY COMPLETELY 100% DRY before applying the tape. If you don't wait long enough that polish will peel up when you remove the tape and completely ruin the manicure.
Quick tip: try applying your base colour in thinner coats. Thin coats of nail polish dry quicker than thick coats.
Good Luck!
