The crescent moon design is done with "oui Madame" (Essie) and "black swift" (milani). I really love how both of these came out. The only thing I would change about the gradient design would be to do it with smaller glitter so that it would be easier to work with.
The last mani in this post was one I did on myself. I didn't really like how it turned out so it didn't last long. First I applied a couple coats of "oui Madame" and then I sponged a thin layer of "golden vision" (Avon). Then I wrote peace on one hand and love on the other with (rimmel) "black satin" but peace looks more like place to me...fail. I liked how the mani looked before I wrote on it with the black, so maybe I will do it again and stop while I'm ahead.
