Our band recently put together a new scrim set up as a backdrop.
Consists, very simply, of 4 pieces of1/2" pvc piping (tubing)these are joined (2 each) as an "X", over which we stretched white spandex material, about 6'x6'. They have the appearance of sails, behind which we use triggered lights or still lights(depending on the song). Looks very good.
Also...hides the amps quite nicely, so the stage is very clean.
Good luck with your endeavours.
