I am having a kids party in the day and want to project onto fabric from behind and put the fabric on the inside of the house with projector inside where my sliding glass door is. The kids can see it as they are playing in yard. I have a benqw6000. the sliding glass door opens to the patio and has some shade with overhang. What is a good cheap fabric? any ideas how to proceed? I may also use the farbic later for outdoor events so I can get it big now, but what is optimal for my projector in night outdoor view? 200 inch diagonal?

Thanks,
damthrill

200" is up there.....but doable under most circumstances.

Recently we have explored the use of White Tarpaulins used a Billboard Sign material.

Follow the link provided to acquire a bright White vinyl coated Tarpaulin 10' x 22' for $25.00 eek.gif

@ 16' v 9' you'll have 220" diagonal. cool.gif

PS. Use the smooth, white vinyl coated side.

No. Sorry...I missed that part. Blame it on the new Forum formatting.. Yeah....that's my story and I'm stickin' to it.

To get some pretty ideal material that's affordable, for that you'll need 4-way Stretch Gray Spandex. You can get some pretty big pieces, but I'm doubting you find 200" diagonal's worth.

Really...the only thing else suitable that even remotely approaches the size you want is commercially available Rear Projection material. The most affordable of which will come from a source like this:

http://www.rosebrand.com/product2780/Aglo-IFR.aspx?cid=219&idx=11&tid=1&info=Front%2b%2526%2bRear%2bProjection%2bFabrics

@ $54.60 per yard....with a yard measuring a full 196" wide x 36" , you'd need to order 3 yds to get 108" x 196"

Did you go to the Link and use the Drop Down menu?

It also comes in 122" widths @ $38.50 per so 2 yds can achieve 138" diagonal via a 140" x 72" sheet.

But that does not allow any extra at the edges for attaching / hanging the stuff. If your going to want to do RP in the size you do, and you want specifically good performance, you both need to use a dedicated material and purchase the amount needed...or otherwise reduce your size expectations and go with 135" diagonal (118" x 66") so you can at least have 4" of extra width (2" on ea. side) and 6" of extra height (3" top & bottom) to attach the material to some sort of rigid permanent or temporary frame.

Face it...this is actual Rear Projection material so you "WILL" get what you pay for. But to get what you want....you "WILL" need to pay for it. There isn't much of any other alternative available in the size your considering. As in "nothing."

that seems good. I am not super picky and am willing to drop size a little for price savings. That rosebrand looks like it is the ticket. I was hoping there was maybe something like this at jo anns fabric, it is local...

thanks,

They very well might be....so if time allows....request / get a Sample, and take it in for a comparison.

Celtic Cloth has always been popular material in Stage Production environs. It's been used / spoken about on both Screens and DIY Screens since the beginning. And you bet, others have done what you yourself are considering....down to procuring samples and finding lower cost alternatives. In this sense, what goes around, comes around. Very, very little is new "under the Sun"....but often time makes info contained on related Threads / Links subject to scarcity.....or downright obscurity. In this case, my not recalling the Threads where there is info on where to obtain the largest possible width Bolt of Fine Mesh 4-Way Stretch Spandex. For that stuff works spectacularly great for the dollar invested, as several with "Spandex - Acoustically Transparent Screens" will testify. But that size issue....that's the issue. I'm believing you can get up to the 180" size with specially "Inline ordered" 4-Way Stretch Spandex. O seem to recall that a 96" wide piece of 4-Way Spandex X 12' (4 yrds) can easily stretch out to those dimensions. But don't expect to come close to getting even 140" diagonal with the size material available from JoAnns or Hancock Fabrics. And if you did, be certain that the material is gonna be more Pricey locally as well.

Getting samples can be fun, and take less time than one would imagine....or it can be a time consuming drudge at best, and a disaster at worst if a poor choice is made. A quality image via Rear Projection is something to wanna have. But there are limits as to how much is really "gained" by saving, while much is lost "visually wise" So unless your willing to just take a suggestion to breast and go for it, the responsibility lies in your decision making process. Keeping that in mind, the idea of taking one's time and finding out / confirming which material will do a "more than acceptable" job for a lot less money.

The supposed "Fun" in all that is the potential of someone finding a "more than acceptable" alternative to a expensive Mfg item that comes in at a fraction of the cost (75% less)

...and brook no mistake. When that happens, people do in fact get very happy. biggrin.gif So it's worth exploring your options if you have the time and the varying amount of patience needed. Many do not.frown.gif
