You can use nail polish just like you would for a normal nail. There are countless designs you can create, and you don't need to bother with a base coat when you're using tape. Pick your favorite colors and start decorating.  Always wait for one color to dry before you add another color on top of it. A clear polish after everything is dry will make it look glossy. Since you already have tape, why not try a decoration method that uses it? You'll also need a small, plastic straw and a layer of newspaper to work over, since this method is messy. This works best with several colors of nail polish.  Surround the fingers around your nail with more tape to protect them from the polish. Be careful not to overlap the tape with your fake nail, or you could tear it off. Dip a thin straw in nail polish and blow through it while it's just above the nail. This will splatter the polish over the fake nail. Repeat with other colors. Since the tip of the straw has polish on it, you'll want to put the next color on a plastic plate or bit of newspaper, then dip the straw in that instead of directly in the nail polish bottle. When you're done, let it dry, then remove the tape protecting your fingers. If you don't have nail polish, you can decorate the tape with small stickers. You can try writing on it with a permanent marker, but it will most likely smudge unless you very carefully put a second layer of tape over the drawing.
