Okay so I'm not an nail artist but I love to decorate for the holidays. This is a really simple way to do it and for not a lot of money.
I used
Jamberry Nail Shields. And it's sort of like contact paper for your nails. You simply cut them to fit your fingernails and then stick them on. You add a little heat with a hairdryer and wah-lah professional looking nails that last for days (okay I should have cut my shields a little larger - next time I'll have my reading glasses on ;)
But these are so much fun for Halloween. I love them.
