I basically just kept painting on the different glitters to build up the layers, overlapping them a bit to try and blend them together (which kind of worked). I like these, but I reckon if I was to do it again, I'd use a base coat of red, as you can see through the glitter in some lights to my nude base coat - a bit more obvious in this next pic.

Pink Glitter (no name?) by w7
Trafalgar Square by Nails Inc.
I finished off with two coats of Sally Hansen's Insta-Dri to make them smooth and shiny. I love this topcoat as it doesn't "split" at the sides like Seche Vite, but it does take longer to become rock hard... it dries, but it will still mark if you knock it for a while after.
One last pic: Here's all my glitters in a nice little row, while I was deciding which to use and what to do! I love all of these and don't use them often enough...
