Hi Myron,
you provoked me to mesure my "scrap". Well, here are my mesures (with a new
digital caliper I finally bought for myself for my camera making...) Inner
cotton/rubber: 0.008 in
Outer fabric:
0.005 in
Both are light proof! Must be different stuff? And my apology to all - it
was 7 years ago I got the stuff from flexproduct, not 12 I originally
stated. Sorry for that Wayde... George.
