Geometric Nails

These didn't turn out quite as I had hoped--I seem to have trouble with masking tape sticking completely to my nails, so some always gets under on one part or another and then looks sloppy. Anyone have a better suggestion?

I started with a base of original formula Sally Hansen Pacific Blue. Then I made a square in the top corner of the nails with Zoya's Neely using the brush from the polish. I then taped off triangles that overlapped the squares after the squares had dried. I thinned Essie's Big Spender and painted the triangles. I finished with a top coat.
