Ombre nails with an eyeshadow brush. Paint your nails with your base color, then apply the eye shadow and finish with a thick clear top coat to lock everything in! The eyeshadow and eyeshadow brush is such a cool technique to use!
Use a bobby pin to make polka dots on your nails. You have to bend the bobby pin apart in order for it to work but after that it's the best thing ever for making polka dots! I did it for my birthday last year!
