I hit a dud on the Shellac front.
Katie and I had both seen several photographs online of some cobalt blue nails, an effect that can be gained by layering Negligee over Black Pool. If I twist my hand in just the right direction, yes, there's a tinge of blue, but nothing dramatic.
It wasn't a total loss. Once we realized that the Negligee wasn't so sexy, Katie suggested putting Moonlight and Roses over the Black Pool. THAT looks nice, kind of a purple metallic.
Pictures of both tomorrow.
