To get nails that look like they cost a fortune at the salon, you just need tape and some craft scissors.
Cut the tape with patterned blade scissors in lengths that will fit the entire length of your nails. Paint nails the color that you want on one side and allow them to dry. Once dried, apply the tape to each nail and paint the second color over the open side of the nail. Once dry, remove the tape and you have two-toned nails that are easy and perfect.
