I was backstage at NYWC in Atlanta this past fall and noticed something interesting about their stage design which I thought could be implemented in any youth room out there.
They had, what I can best describe as, sheets of the replacement metal screens you put on screen doors. Crinkled them up, hung them, and then shots lights on them. It gave this cool backdrop illumination. Usually you can find these replacement screens in rolls without any problem. Just pay attention and do not buy the plastic screens, won’t work the same. Not sure the cost but it isn’t more than $20/30 for a roll. Probably would need at least three rolls to fill a small stage space.
