The base color is Sally Hansen Black Out. I used a little green glitter polish from Snowman Nail on my pinky and thumb. I used a tiny nail art brush and Sally Hansen White on to write Bah! Humbug! on my index, middle, and ring fingers. (I forgot the exclamation marks, though!)
Warning: Be prepared to be called Scrooge, Grinch, etc. when wearing this design. Some people just can't take a joke. Ha ha!
