Drapery taller than your
stage, hung at
fullness off center, swagged and weighted to the floor to create a "swoop". Any color other than black. Could also be done with a
scrim, provided that yours is a
traveler type and the
batten can be brought in to give you room to
swag.
Colorful oriental rug, jauntily angled under said mic and stool. Sometimes rug companies will rent them, or you can
pick up an ookie stained one for cheap, pay to have it cleaned or hose it off in the parking lot. Stains and wear matter way less at 30'+.
Colorful Lycra panels, grometted and tie lined or paracorded into weird stretched shapes. Doesn't fray, so no hemming necessary. Overlap multiple panels on multiple planes and angles for added oomf. Check your local codes for flame retardant requirements!
Build a couple flats with the 1x4 framing laid
flat. Paint the
luan one color, the frames and cross members another, hinge so that it's all visible, and you've got a couple folding screens. Could also use cheapie beadboard paneling, and rub a
glaze into it to
pick up the grooves. Reverse side is usable later as a regular
flat.
Embossed or anaglypta wall paper on flats. Add
trim to create a faux Victorian
flat/
screen
Hemp ropes swagged from battens to offstage, can be accompanied by real
canvas sandbags stuffed with something not heavy. Adds a vintage hemp-house aesthetic. If you don't care about reducing the strength of your white nylon ropes, rub them down with wood stain to get a similar look.
Hang lights from aluminum
truss, even if that's then hung from your battens. Instant industrial chic.
