Based on the current drawing, my drum cloud is a 2x4" frame, with one sheet of rockwool in between each "rib" of the skeleton. I'd like to be able to use less internal bracing, but am wondering about sag. Again rockwool is 6lb. density and 2.5" thick. Anyone have any ideas as to how many continuous sheets I can have without support? The other cloud above the door has strips approx. 2' x 7'...basically two sheets in series the long way, I figure that should be good. Maybe the same structure over the drums as well?

Oh, the fabric covering is likely to de burlap, but I have not ruled out muslin.

On a side note, if each sheet is individually supported, do you guys think I can get by with a jersey t-shirt type material without sag?

Thanks,

John
