How I Made A Lit Prom Sign

A quick and easy build for my local high school. The cost of renting a lit up prom sign was $900! That's crazy! Instead of renting, I made a set of letters they can keep for less than $200 in material cost. I donated my labor cost to help out. 

Each letter is made from 3/4" melamine and lit with a chopped-up string light kit that was provided to me. Each letter plugs into the next one so next year it can be used without the 22. Or a 3 can be made to add to it.
