Anyone know or used a fabric that can give the most invisible, infinity black background for close product shots? I want the product to look like it is floating in invisible blackness. This is not for people shots as the product will have to sit on the fabric itself as I will shoot down on it. Actually doing video and photography with it so the fabric cannot be reflective at all.

I know black velvet is a start, but I went to my local fabric store and the black velvet there was too reflective. I would imagine a video or photographic company sells or recommends something for this purpose, but Ive looked at B&H and am not sure. If you know of something polease help me as even online fabric stores have many different velvets and have not been able to tell me which one will fit my needs best.

Thanks for any help!
