I used two coats of Pretty Edgy for the base and waited several hours before the accent. I simply placed scotch tape to the desired angle and painted! It's good to wait about 5 minutes before taking off the tape - and peel it in the same, angled direction. For the second stripe, I waited about an hour before applying more tape. Same process, different direction!
Finished it off with Sally Hansen Mega Shine, as usual!
