This is a fun and easy way to create a new summer look with your old sunglasses. Simply get two similar shades or completely opposite colors of polish. Apply one color to the top of the frame and the ear pieces, let dry and finish by adding the second color to the bottom half. You can place painting tape over the top layer to create a smooth and straight line or cut the tape so that it has zigzags and them place over. Also try using one of those scrapbook scissors with the fancy edges and place that over the top layer to create an even cooler design.
