BLACKOUT
MATERIAL
More correctly should be termed `dim-out'. This is 100% cotton Bolton Twill fabric, treated for light-proofing and flame-proofing. A single thickness used as a blackout will let the odd pinhole through, but be adequate for working with papers. If absolute blackout is needed, any form of lining will ensure this, or the use of a double thickness. Velcro, which can be obtained in reels, is one suitable way of mounting the material into a window space. Supplied in a 60'' width, by the metre (3'3'').
