Here's a new idea. An all-in-one stand-alone background kit. It's available with a Chromakey green cloth, black or white. The frame collapses into a small bag, and is very lightweight.  This unique system provides quick set up and tear down with telescoping legs and arms, fitting backdrops up to 5' x 7'. The kit includes a 5' x 7' backdrop that incorporates grommets along the top and bottom for easy hanging and a taut fit. Backdrops are machine washable in cold, tumble dry low. The carry case is good for travel and can fit the X-Drop system and up to 3 backdrops.

       

Prokit sells the Westcott X-Drop Backdrop kit for £99 + vat.
