I know I wanted to have a base of blue, so I started with two coats of Tip Top Blueberry Pie.
For the geometric part, I painted Tip Top Hysteria and Armourplate on a thickish plastic sheet and when that was dry, peeled it off and cut it into random shapes. I did the same with Hean #225.
I then randomly stuck the shapes on, overlapping here and there. On my ring and pinky I stamped using plate M73 from BPS. The the top left image looked like blocks falling down, so I decided on that and stamped with Tip Top Jazzberry Blue.
