One of our recent purchases was a digital projector, so we could play movies outside. There are all sorts of options for exterior screens but I wanted one that I could put up and take down easily and that would fit within the pergola, along the back of the garage. I decided to make one to fit the bill.
The process was pretty easy. For the screen, I used black-out cloth. We got ours online, through Amazon. They sell stuff for "Carl's Place". The other items I used were two ten-foot lengths of PVC, two 10' packages of heavy-duty velcro, two eye-bolts and two screws.
I mounted end of the screen directly to a piece of PVC with the velcro, making sure that I was mounting the back of the screen so that the front would roll over, concealing the joint.
