Jeromina's timing is perfect for two reasons: Valentine's Day is on the way and red Christmas lights are on clearance - score! She made this wall lamp for less than $3 and her version doesn't require any special tools or skills (not that she doesn't have them because she does, in spades). Make a visit to her blog, Paper, Plate and Plane for photos and instructions. You really could use her idea and method for any shape or colored lights you want.
