I am after a highly retroreflective grey fabric, but only up to quantities of 100m. Must be over 1m wide, maybe 1.2m or 1.4m (preferred). Wider is better - less seams whens it's sewn together. Needs to be evenly reflective across the fabric or it will not work for digital video. I want to build a system similar to Datavideo's Chromatte, with a LED light ring - as I do not like the cost of their system.
