Yandood Black Flocking Adhesive Tape 3in x 30ft Projection Screen Felt Tape Border Ultra High Contrast Deep Black Felt Strips for Projector Screen Frame DIY

I wish I hadn't waited so long to add a border to my screen. Looks much better now than just with the screen alone. This stuff is pretty dang black too. It does a good job of absorbing some bleedover from your projector, but recognize too much overscan will still reflect off of this a bit, but it's a lot darker than the screen so it will look better. Keep your overscan to less than 1/4" and you won't really notice. Much better than overscanning onto the wall behind the screen. What it does do well is absorb the black letterbars from content that is not 16:9. So a dark image is completely lost in this black border. They claim that the darker black border makes images look better or that it adds contrast, which if it does it's an optical illusion as this product by itself cannot improve your projector's native contrast ratio. It does actually look better to me, whether it just looks better sitting on the wall as you're watching a movie, or that it just gives the experience more a movie theater feel. The stuff stick great and had no issues sticking to 1x3 common pine lumber. I didn't actually stick this to my screen, but to a 1x3 pine border that I added to screen, so that it wouldn't make the screen smaller. It's only 108" diagonal but with the extra 2.5" all the way around, it looks bigger. The 3" wide stuff was plenty wide for me, couldn't see the need to go to the 4" wide stuff. And since the 1x3 lumber is actually only 2.5 inches wide, I ended folding the last 1/2 inch around the sides. So far it's been sticking great. Super easy to install. Cut your ends at 45 degrees to make it look like a frame. Overlap both sides then take a blade of exact zero to cut through both pieces. They will line right up. Not sure what else I can say about this product. Price is right and finishes off an otherwise unremarkable white screen. Can easily recommend.

It’s perfect, super sticky (it’s on a concrete wall surface)

Great border tape.

This elevated my white screen to a 10/10. This was easy to work with. It is very very black, and illuminates any light overspill with my projector. These pictures don't do it justice. For the price this stuff is amazing.

I used this to flock the interior of my newtonian telescope, looks great and reduced internal glare a lot.

I like the smoothness of velvet and also dimensions and length is perfect for big size -130 inches projector screen. However, the material is not sticking to fabric and every time I have manually press which is very annoying. This ruin my DIY projector screen.

Time will tell if the adhesive works well, but the initial application is outstanding! I had built my screen years ago and was satisfied with it never getting around to building a border or wrapping it so when I saw this on Amazon, I took a chance and have no idea why I didn’t know about this product years ago. It changed the room in a dramatic way, I would imagine any DIY screen or painted wall would benefit from this rich and dark felt absorbing overflow light. I had a good picture all along, but now it is outstanding and looks a heck of a lot better projector on or off .

Wonderful for flocking a telescope. There was enough in here to do a 10-in dobsonian and a 6-in Newtonian and some leftover still. It is a little directional though, one direction is more matte than the other for light reflections. You want to arrange this so that the mirror has the darkest view. With the whole telescope disassembled you want to look into the tube from where the mirror would be and from that vantage point it should be the darkest to be installed correctly. If your telescope lacks baffles this is a great option. I did the 6-in myself but the 10-in I had to have my wife help me.
