I do something a little more simple and faster. I don’t use cement, drills, eye bolts, 2x4’s, buckets or bed sheets. I use a telescoping back drop frame (roughly $80 to $180 depending on how heavy duty it is), a screen up to 150” elastic projection screen (price depends on the size of screen but all screens are a cheap price for their size) and elastic backdrop clamps (about $10). I also put more grommets in the screens to get as many wrinkles out as I can. They never seem to put enough grommets in these screens. So I had to get a grommet set at one point (I can’t remember the price but that was a one price deal for many of my screens. Yes, I have more than one screen, all different sizes), Put the frame up, put to whatever size it needs to be, attach the screen, adjust the clamps and frame to get all the wrinkles out, anchor the frame in place so it doesn’t fall over (I’m lucky enough to have something behind it to tie it to like my porch railing so it doesn’t fall forwards and it’s always on a piece of land that has a slight down hill run so it won’t fall backwards), set up the projector and you’re ready to watch a movie. Takes roughly an hour or so to set up (maybe longer depending on how perfect you want it) but it’s easy to put up, easy to tear down (so it’s not a permanent fixture in your backyard and it’s portable), easy to store away (everything comes in a bag and it’s pretty compact when everything is in their bag. A closet or under a bed will store it just fine) and it’s well worth it.
Glad to hear that you're going to try it! We used a full size sheet, so 54" x 75". You could probably use a twin size, but anything bigger than a full would be too tall for the boards.
Whatever works! This method is great for people who want to put a screen in their backyard, but a garage should work fine. It may be hard to get the screen tight with just tape, however.
You can, but your screen will be considerably more wrinkled. For us, the rope was essential to keeping the sheet tight. Also, it will add stability on a windy night.
