When I hang a roll of seamless background paper on a backdrop support, the weight of the paper can make it keep unrolling. What’s a simple way to hold the roll in place during a shoot?

If the crossbar is fixed and won't rotate (e.g. it has a pin though it), using an A-clamp to secure the paper to it will often work.
If the crossbar can rotate (or the A-clamp doesn't have enough grip or surface area to keep from turning itself) set the clamp so the handles brace against the upright support (or around the knob on a C-Stand). Make sure to do this on the back side so the handles are in contact with the upright support immediately.

A simple fix is to use an A-clamp on the roll or crossbar to stop it from turning.
- If the crossbar is fixed and does not rotate, clamp the paper to the bar.
- If the crossbar can rotate, position the A-clamp so its handles brace against the stand upright (or a C-stand knob). This physically prevents the roll/bar from turning.
- Place the clamp on the back side so the handles contact the upright support right away.
The key is not just gripping the paper, but stopping rotation. If the clamp only squeezes the paper and the bar still turns, the weight of the roll can keep feeding paper out. Bracing the clamp against the stand is the more reliable approach.
