Anyone have a more detailed summary of the things to buy to make your own Projection Screen?

I purchased enough blackout Cloth to make a 100" diagonal, 16:9 screen (probably enough to make a 120" really... but I want a 100" )

I plan on getting decent sized wood, metal support brackets to secure the corners after cutting the end at angles, then using wood slats to frame it corner-to-corner for added support..... and I plan on drilling into a slanted ceiling, and connecting "hooks" to the studs in the ceiling, then connecting hooks to the top of the frame on the screen..... then hang the screen from the hooks with chains, painted flat-black, so I have full control of how far from the floor-to-ceiling I can adjust the screen.....

Anyone have a better method for mounting a DIY screen from a slanted Ceiling? It's an Attic room that has been converted into a bedroom, with separate room, and bathroom.... I'm going to have a 12' throw distance to get my 100" image from a Mitsubishi HC1500 projector.....

I was thinking about putting a black border around the screen too.... but I think I'll wait until I get the screen up, and start "tweaking" before I do that.


Anyone build a screen, and have any useful suggestions? I need room under the screen for my Center Channel, since it won't be an accoustical screen material, and I'd like to keep the center channel 36" off the ground or so...

The screen material is at my house, I need the hardware/wood etc.... so I need to make sure I cover my bases before I go shopping. I also need to order the projector mount still.
