Frankenails — Consider this the Halloween version of colorblocking! All this takes are two green shades and a black nail art pen.

To begin, bisect the nail with the green polish in different directions (diagonal, horizontal, vertical). Don't forget to mix up the polish order!

Once dry, draw a thick black line separating the two polish colors. Then, apply hatchmarks for a 'stich' effect.

Cute, huh? For a less cartoony effect, make the hatchmarks more skinny and choose darker green polish colors.
