So my best 'real' friend (as opposed to net friend) is a home cinema nut. In his old place he had a blank wall he used to project onto, but his new place didn't.

Uh oh!

LOL so I believe the exact design brief for this project was 'build me a screen worthy of mordor' with the only criteria that it be bigger than his old one.

So we went to the hardware, bought the longest pieces of wood they had (360cms) and some curtain backing and built this:



And there it's happily stood for just over a year. Last night we rearranged the room (I left at 2am he was still tinkering with the speaker wiring at 3am Tongue ) because recently he joined a home cinema forum and although everyone was pleased with the size of his screen (at first they thought it was a typo as it's 14 feet on the diagonal) apparently the 'aspect ratio' is wrong.

Quick lesson for those that aren't up with this stuff (as I would be if I didn't have a home cinema nut as a friend) a normal tv picture is 4:3, then your widescreen type tv is 16:9 but the cinema screens are designed for 2.37:1 which most films are filmed in.

So naturally he wants he's screen to be 2.37:1 ... which means it needs to be around 70 cms longer.  Shocked

So I have to rebuild the damn thing Tongue and thought I'd share the first version before that happens. Rebuilding is set down for may.

I do have a couple of questions though if anyone out there can help me Smiley Does anyone have any ideas for joining two pieces of curtain backing with a near invisible seam? See we can't get curtain fabric wise enough (150cm wide was the widest we could get) so I had to put a straight seam to get a sheet large enough. Once stretched over the frame it's not too noticeable and with the old projector it was not noticeable. But the new jector is brighter and the seam is visible. Any ideas how to minimise the seam line or make it pretty much invisible would be great!

Please let me know your thoughts.

Not sure if this would work... but could you paint the whole thing with gesso?

I had a tent made once to my specifications by a canvas place that did awnings, tents (der) etc so whilst i have no ideas about invisible seams maybe someone like that would have fabric that wouldn't need a seam. (This is all assuming he doesn't want to correct the width to the existing length. Yep this would mean smaller. Probably a no go huh?)

Could you sew it, then cover it with maybe another strip of fabric over it with the same fabric and attach it with that iron-to-fuse-fabric stuff. Wow. I hope you can understand that, I can't think in a straight line tonight.

Hi guys, thank you for the suggestions!!

Not sure if this would work... but could you paint the whole thing with gesso?

Yeah that's his thought, I'll look into that more. I wasn't sure how hard it would be to make sure the surface was smooth.

I had a tent made once to my specifications by a canvas place that did awnings, tents (der) etc

We've been looking at sourcing a larger piece, this would definately be the easiest to work with if we can find it. So far we've only been looking at curtain fabrics, we definately should look at ccanvas and tent suppliers too, Thanks Smiley

(This is all assuming he doesn't want to correct the width to the existing length. Yep this would mean smaller. Probably a no go huh?)

Oh yes smaller is against his religion!

Could you sew it, then cover it with maybe another strip of fabric over it with the same fabric and attach it with that iron-to-fuse-fabric stuff.

Smiley Makes sense to me Smiley Yes this is what I was thinking. I was a little concerned though that the glue or fusing webbing stuff may degrade and fall of over time. Sad I know so little about these things, do you think it would stay?

you can always try a set props store. i'm not sure what the exact name is, but my husband who is a film maker bought his green screen online, expensive as hell, but it's much wider then the 55" the fabric comes in in stores.

This might be a dumb question but where do you find curtain backing?

I was going to suggest he look into reflective paint.  It has little glass beads in it and it makes for a better projection surface.  But you don't have to buy the expensive stuff they try to sell to home theater buffs, a cheaper kind will work just as well.

I'm like 84 years late for this party, but it's interesting because I happen to have this other website pulled up right now, with fabric that's 108 inches wide (274 cm) that's made for making bedsheets, I guess. And it's really pretty inexpensive, about $6/yard with $5 shipping in the US. I'm thinking of using it for a canopy thing in my yard for a party, but it might be ideal if anyone else is thinking of projector screens.

The fabric might not be as thick as you'd want so the gesso idea would come in handy there, or reflective paint.
