Tiger Stripe Design
Step 1: Paint your nail a solid color
Step 2: Take the black, and starting by your cuticle make a jagged triangle coming off one side of your nail, and going towards the other side getting narrower. By changing the angle of your triangles you can make your design look very unique each and every time. Make sure you squeeze the tube the whole time you design. Be sure to fill in the triangles as you move on. (Leave the middle not filled in on a couple of triangles, and you'll have another stripe design).
Tip: Be sure to squeeze tube when putting the brush back in, in order to release air bubbles.
