    Just got a sample of some Devore, jeez it really is very black! Completely agree that it makes everything that was black before now look grey. The pic shows PSM border tape which genuinely looked very black a couple days ago, but against the Devore there is no comparison (which actually looks even blacker in real life).

    Got 3 samples coming from Minerva Crafts and also a sticky-back Flock material, will be interesting to see if anything can hold a candle to the Devore. :thumbsup:

    Hi Alan,

    (Apologies for the unrelated question, guys)... What type of projector rack is that?

    Thanks Allan

    Back to the thread topic, I checked out the black fabric at one of the local fabric stores (here in the middle east) and they had a really good fabric... The called it "black suede"... Took it home and it matched the borders of my projector screen in texture, but was very slightly darker... :D

    I only used enough to cover the border spill-off areas when zooming in for scope movies... Solid results. Much cleaner look. Might get more even though the projector is in a temporary set up.

    I'll see if I can find the brand/fabric code. It cost me the equivalent of £9 per metre. It is most definitely not accoustically transparent though, but works for my purposes ;)

    Do you guys find covering the back walls makes a big difference? I suppose that depends on the distance from the screen. Mine is quite close at 3.6 metres. (wide but short room)

    Hi all,

    Can any anybody link me to the IKEA black rugs that people have mentioned before please?

    Ive had a look on their website and am not sure which particular piece people are buying.

    Cheers

    Ahh thats perfect thanks!

    And these really are the best things for blacking out the area under the screen then?

    Im aiming to place Devore all over the walls and ceiling but i cant see it being suitable going on the floor. Or can i :laugh:

    I should put this in the classified but I am not sure which section.
    I am after a piece of Devore about 500mm x 300mm. If anyone has any spare I would be willing to pay.

    Edit, just bought some of the micro velvet off of eBay.

    I prefer the eBay stuff. I have both in my room. Devore is too directional and only marginally darker, so in most applications not as good.

    I have now got both the Devore (thanks a million @Trojan) and the eBay stuff. To my eyes the eBay stuff is not as black as the Devore. In isolation the EBay one looks really good but the Devore has the edge.
    Here’s a picture, Devore on the left, they are much blacker in real life.

    Well your room was certainly very black and the EBay one is more than half the price of the Devore. If I was doing a whole room I would agree the EBay one would be fine.
    Unfortunately my wife won’t let me completely black velvet the living room :laugh:

    I came to a similar conclusion - I was going to use the Devore around the screen, and the ebay stuff for the rest of the room, but after trying the ebay stuff around the screen, and seeing that it didn't reflect any light, I didn't see the point of buying the Devore (the whole room is black velvet). My screen is literally wall to wall with the black side wall panels acting as the side masking, so the screen surface goes right up to the the ebay black velvet. There's no visible image on the velvet so it does what is needed. When a movie is on, the side walls look more like the screen wall each side of the screen and makes the room look wider.

    In isolation when tested against each other on a totally flat surface, devore IS slightly darker.

    This isn’t my issue with devore, the issue is as soon as you put any type of crease/curvature into the material, the directionality of it starts to look too obvious.

    Strangely, the darker your room, the worse this highlights the issue. When your room is completely dark, the projector light really starts to light up the non reflective areas of devore so it starts to become obvious.

    Personally I think Devore is a horrible material to work with, the eBay stuff is much easier.

    I’ve also found (2 seperate orders) that the consistency of devore has been awful. Crease marks, lighter patches, etc.

    Again, not massively noticeable until you put it in a room and the projector lights it all up.

    IMHO save your money and get the eBay stuff.

    Yes, I bought a lot of mvel22 from TiaKnight fabrics directly (it was cheaper than ebay then), though I think it was only 44 inches and not 58. If it's mvel22 I would think it was the same fabric, just wider. You can always ask them directly - they'll send you a sample if you ask as well.

    This is all very interesting...
    I found the nap on the Devore material a pain. You get different results depending on the direction you have it. So you must make sure it’s all hung the same way. Also there are batch issues. Some darker than others. Plus I was trying to use as much as possible and the Devore has machining issues along the edges. Maybe 1-2cm. It’s where the nap is uneven. This shows when the room is lit normally (if your looking for it) but not from a projector lit room. If i do my room again I may try the eBay stuff. Must get a sample.
    But I’m happy with the room so maybe not lol
    Are there nap issues with this material?

    Got a sample of MVEL22 direct from Tia Knight. Thanks @Peter Parker for posting the link before.

    My experience pretty much mirrors everyone else. The Devore is very slightly darker when viewed head on, but when viewed from off angle the MVEL22 actually looks darker.

    I have today checked both materials for acoustic transparency as i intend to use one of these to build my baffle wall and again the Devore is very slightly better (0.5-1dB less attenuation at high frequencies) but no where near enough to matter imo.
    Devore vs MVELL22.jpg

    When you take into account the price of the MVEL22 is £8pm vs Devore at £28pm (not forgetting the MVEL is approx 1ft wider) it really seems a no brainer to opt for the cheaper fabric.

    I recently got over25m of devore made up as curatins and am very impressed. If I could go back, I probably would have gone down the cheaper ebay route looking at the posts above. Not that I'm not happy with devore, but if the cheaper one did the same job I'd be up for it.

    Few questions though, how do people deal with dark leather sofas? I have some and because the devore is so dark, the projector light lights up the sofas despite their dark colour.

    Also is any black rug going to do the job or is the ikea one really the only way? I ask as my room is quite wide and I'd have to use 2 of the ikea rugs so would prefer a big black rug which does the same job. At present, the floor is really quite annoying given how dark the remainder of the screen border is.

    Just a heads up for anyone thinking about buying the MVEL22 direct from Tia Knight fabrics. The material is 44" wide, not the 58" described.

    I got my MVEL22 off ebay its described as 1.2m wide / 47" on there. Its actually 44" / 112cm wide. Its pretty much the same width as the "Official Whalleys Devore"

    The prices on all these decent velvets seem to have really shot up over the past few years !

    At one point on the Tiaknight store it was £4.99 before it went out of stock, and the same seemed to be happening on ebay too. When they got a new lot in the prices were a fair bit higher.
