Here’s a pretty simple how to for making your own project screen… “Home cinema is a great way to spend piles of money quickly. The projector costs a packet to buy and then more to run (about 10p an hour) and so you really don’t want to be shelling even more money out on a projection screen. A custom made projector screen will cost you around Â£200 at least. I hear you cry foul. Why get a custom made projector screen – can’t you just buy one off the shelf. Well yes and no. If you are going for a small image you can buy one off the shelf.” Link. Also, check out the Tyvek version on Instructables.
