When I was going through my dragonfly phase of mani's not too long ago, I decided to do a gray/charcoal/black combo too....here's what I came up with.
Started with a base of Orly Mirror Mirror, two coats.
One coat of China Glaze Let's Do it in 3D on accent finger.
Stamped! Black Konad special polish using Big SdP M.
I then filled in the dragonfly wings with Let's Do it in 3D.
On the accent finger, I used a darker pink glitter striping polish for some interest in the wings (but unfortunately failed to note which one I used.... I don't think it matters much as its not terribly visible anyway!).
Also added a few random dots using CND Plumville. (This actually reminds me that I want to try to stamp using these CND creme polishes....they are generally one coaters and have some vibrant hues; I'm thinking they'll work well for stamping. I turn to them often for adding dots as they are so well pigmented.)
Another image plate design that is right up my alley right now! Lots of opportunity to see the base colour including layering combinations; then so many possibilities just by changing the base colours, the stamping colour and then adding some cool interest by filling in the wings! And then jazzing it up with a few dots!
Have a great weekend....and thanks for looking!
