I just finished turning the third bedroom into a theatre – as in a 104-inch screen, projector , 5.1 DTS surround sound, etc. – on a small budget and lots of sweat equity from myself and Emily. BTW, no, that picture isn’t upside down, the projector is mounted that way for a reason. If you’re interested in building your own, I’ll tell you the budget way. And if that involves taking out wallpaper, I hope you are filled with patience.
