Pick your two colors. A dark and a light color.
Here are the ones I chose! Silver and a Midnight Blue
Start with a coat of your lighter color and let them dry
Grab your scotch tape to create your design (leave some tape hanging off, so you can peel later). I just wanted a simple silver stripe down the middle :)
Add your dark color on top!
Wait for the dark color to dry, peel off the tape, and VOILA!
