I'm looking for the material that was used for the light traps in European single sided metal film/plate holders and inside the backs of vintage Plaubel Makina cameras. It is not a foam material nor is it exactly felt. Upon looking at it very closely one can see that it is a pile material much like carpet. Felt is a laid material of random filers much like paper is made and is flat on top. This is fuzzy with densely packed threads sticking up. In my Makina and the holders its about 3/32 - 1/8th inch thick. Anybody have any ideas? thank you!
