all of these deco shapes and lines can be done by just using tape. cut out any shape you want and put it over a base layer. give it two coats to make sure you cant see the base color coming through. peel the tape off while the polish is still damp or else the polish will dry and rip up the base coat along with the tape. throw on a good top coat (always splurge on a good top coat) and voila! everyone will be asking where you got that done!
