What is this backdrop made of?

It is a printed fabric backdrop, the type meant to be hung on a wall, frame or stand. It is not a rigid panel or a vinyl floor mat.

Can I use it outdoors?

It can be hung outdoors in dry, calm weather, but printed cloth is light and will flap or tear in wind. Anchor the edges and bring it in if rain is likely.

How do I get the fold creases out?

Hang it taut and steam it, or iron it on a low setting from the back with a cloth between the iron and the print. Give it a day hanging to relax before a shoot.

Does it come with a stand or frame?

No. It is the printed backdrop only, so you need your own backdrop stand, frame, tape or pins to hang it.

Is it big enough for group photos?

It is sold as an extra-large backdrop, so it covers a wall or a group shot better than a small portrait drop. Check the listed dimensions against your space before hanging.
