Here is 2 coats of Hannah Pinktana over black.
This is how I cut my tape to do this design
You then tape it on your nail, like so
Once you polish on your 2nd color, black in this case, remove the tape ASAP, and you will have this
Repeat this for all your nails, and once you're done, add your top coat, mine is SV, Seche Vite
