Dyed Collapsible Reversible Backgrounds This extensive range of collapsible backgrounds gives photographers the colors and patterns to express their creativity. The 6' x 7' (1.8m x 2.15m) backgrounds with train have been modified and now use Lastolite's knitted "crease resistant" fabrics (currently used on the 5' x 6' backgrounds) making it even easier to work with the full length collapsible backgrounds.
