Mark Borgetti from Joy Lutheran Church in Gurnee, IL brings us this butterfly design.
They started by free handing the wings on the four pieces of Coroplast using the smaller image and a grid as a guide. The black was a combination of electrical tape (for the outlines and thinner areas) and contact paper (for the larger areas). For the circles, they simply cut away the contact paper.
Can you tell me more about the lights? Are they shining from behind or in front or both? What kind of lights did you use?
