I'm on my way out the door to Nail Night, but first, a quick post. I've seen a lot of example of layering glitters on blogs, so I decided to try it for myself in this manicure.
The glitter I chose for the first layer is Finger Paints Purple Palette, a light purple, very sheer jelly base packed with small medium purple glitter particles mixed with some small silver glitter. This applied very easily, sliding on smoothly and not running at all. Given the sparkle, it wasn't easy to see through after two coats. I think it would be basically opaque at three coats due to the density of the glitter.
On top of Purple Palette, I added one coat of ELF Golden Goddess, which has a clear base with small gold glitter and larger gold holo hex glitter. The layering made the purple of Purple Palette look a bit lighter and added the extra bling of larger particles and a flash of holo. I finished with two coats of Sally Hansen Quick Dry Top Coat, which is thicker than Out the Door. After two coats, this was totally smooth. As you'd expect all this was pretty hard to remove.
This combo was SUPER blingy and caught tons of light. However, Purple Palette is pretty sparkly on its own. Overall, I think Golden Goddess would be put to better use over a nice creme or subtle shimmer. Used that way, I think it would look great as part of a holiday manicure.
