Black Fabric for magic mirror

[M4nik]

Hi all,
I need black fabric that light can’t pass through it so I can display my monitor behind mirror. My Monitor is small for the mirror I built so I need black fabric to cover the mirror on one side. I would like suggestions where I could find a material like this.

I used black construction paper and that works well and is cheap

Black clingfilm. I used.

I just have a black MDF plate cut to the right size.

Personally, I’d just paint the box it’s in…

I took the protective packing material which was delivered with my mirror. The mirror was wrapped in several layers of a kind of thin black Polyurethan mats, which were perfect for using them to cover the back.

Black construction paper worked for me. Put it behind the mirror and no light goes through it.
