Here's my entry: a dark blue-light blue gradient with sleigh and reindeer silhouettes and random snowflake branches. The idea was Santa returning home after delivering gifts all night, as dawn is breaking :>
For the gradient, I used China Glaze Kinetic Candy again and sponged on L'Oreal Colour Riche in Jet Set to Paris (I'm not the only one amused by the funny coincidence of this polish name, right?) I initially picked China Glaze Up All Night (again, oddly fitting) for a deeper, darker sky, but it leans a little violet and clashed with Kinetic Candy. On top of the darker blue I layered Layla Pro N.22 (Glitterland), a topper packed with super fine and small circular silver glitter, for stars and a little holiday sparkle. I used Sally Hansen Xtreme Wear in Black Out for the silhouettes and Sinful Colors Snow Me White for the snowflake. Ordinarily I would use black and white acrylic or liquid acrylic paints for a smoother, more opaque result but didn't want to risk running into trouble for not using nail lacquer.
I kinda wish I had dotted a little red glitter nose on one of those reindeer! What would your holiday nail art look like?
