Admittedly, my nail art skills pale in comparison to Amanda's. These old(er) hands can't hold the paintbrush as steady as a 20something. ;-) But here is a cute design I saw on some holiday plates that I wanted to recreate on my nails.
I started with a base of OPI Alpine Snow matte. As usual with white polish, I had some minor issues with streakiness and patchiness necessitating 3-4 coats.
Then after the base was completely dry, I painted a stripe of black acrylic paint at the base of my nails for the hat then used a dotting tool for the eyes and a thin striper for the smile. The carrot nose is made with orange acrylic paint and a small nail art brush.
I first attempted this nail art with actual black polish, but found that it was too streaky and didn't cover well so I switched to acrylic paint.
