It can't be sold/recycled as easily, but with a few pieces of wood and a staple gun you could stretch the fabric over a wooden frame and staple it to the back. Almost like stretching canvas for painting.
That's some great content, man! Keep it up. I did similar when I started! For the projector, I had gotten a used Epson 915W on Ebay for like 200$ CAD. Was extremely happy about it back in 2017, I just changed it today and resold for 210$ and bought a pizza :)
I would avoid those no name projectors and go with a used name brand one from the likes of Sony or NEC. You can get old XGA or WXGA ones very cheaply or sometimes free from schools and businesses that are upgrading, usually with plenty of remaining lamp life, and they will output thousands of lumens rather than hundreds. The cheap projectors more often than not have a native resolution of something like 854x480, and a very poor contrast ratio. I think you ended up with one of the better ones based on that image.
Iam building a budget home theater system right now i have a budget 1080p vankyo projector and a 120inch projector screen a xbox one s gaming system cable box and a 1080p roku streaming stick iam about to buy onn dolby atmos sound bar from Walmart in some months iam going to a 4k projector
Sir when the projector say it supports 1080p it means that projector will display the 1080p source material but the native resolution will be the projector native resolution your projector is 720p
