I am not a big fan of the genre, but long ago, I watched Hitchcock's movie Birds.
It may not be your run of the mill horror, but it is a classic! That movie left such an impression on me, that even decades later I still feel uneasy passing large gatherings of birds. Especially crows! They just creep me out! So, for the fans of black and white movies, Hitchcock in particular, black and white manicure.
I did my background by dropping white (Essence - Wild white ways), light gray (China Glaze - Pelican gray) and dark gray (Nails Inc. - Thames) on the piece of parchment paper, squishing it with my stamper, then dabbing it onto my nails. Result is marble like background, which in this case represent cloudy sky.
I stamped with black Mundo de unas images from BP-58 and Helen 09 plates.
