Quick post to write up how I built a retractable green screen mount on my wall for not much money. I bought a mounting bracket from Amazon that was intended for paper photograph backrounds like this. I didn’t want paper, I wanted muslin for it’s superior light disbursement and durability. I already had a 9’ by 15’ muslin green screen backdrop similar to this one. When the mounting bracket arrived, it said to use a metal rod with a 2” (two inch) inner diameter.
