I found these earrings on clearance for $2 awhile back. They are giant circles of red stars. I completely loved them, but the red was pale and tomato soup-colored, rather than a deep red. I also decided glitter would be an improvement. I used some nail polish I already had around the house to give them a good coating.
I had to be careful not to fill in any of the stars. They took about 5 minutes to paint, and about the same time to dry. They are super sparkly and gorgeous now! This picture below gives you a little better idea of the color differences. Quick, but fun crafting!
