Vince Farrell from Christ Community Church in Hopkinsville, KY brings us this Christmassy use of crinkled aluminum screening.
They went to Lowes and bought five 48″ wide by 25′ long grey screen. They cut them in half, giving them just over 12′ in length. The scrunched them up, tacked them on the wall with a staple gun, and used basic Par32 cans with purple and blue gels. Total cost, not counting lights was around $130.
Then they added some Christmas trees with silver ornaments in front to make it Christmas.
