In the shade.
In the sun. My index finger's nail isn't bent like it seems, it's just that I didn't think I had enough silver so I tried to go in with the polish's brush and add some more sparkle. I wish I hadn't though, because while it did look shiny, it made the look messy.
Fail. This was the first hand I tried doing and well, I'll let the picture speak for itself.
I also fudged up by using a top coat other than Seche Vite on this. Other top coats smear the colors into each other if they aren't quite dry, but Seche Vite is great for nail art because it gives you quick dry time without the muss.
