Navy yields a dark room
Navy blue yields a nice dark room even in full, direct daylight. Ran through a dryer cycle before hanging, never notice creases if any remain. Slides onto the "standard" rails (the cheap sort in rentals) with ease; other pockets allow for fancy rods up to a couple of inches in diameter. These do what I need them to do, at the right size (bonus, enough allowance to wrap around L bends).
