Hey gang, I see that you guys use wax paper and such for light difffusion. I work in theatre and we use lighting gel on our lights for colour and for diffusion. If you had any of this at your disposal, a little goes a LONG way. Rosco the main manufacturer of it. Any theatre supply store would carry tons of it. There's over a hundred different colours and diffusions.

The sheets are about 2" x 3" and they run about $10 each. plus, they're made to withstand heat.

And if any of you know of ANYONE who works in a theatre, they always have tons of scraps around.
