I've been playing around with the fire-hose that I got from a fine member here and was thinking. It doesn't lay very flat. The edges seem to stand higher than the rest because of the roll over on the sides. I have some thick material/Cloth. Was thinking of trying to fill the inside of the fire-hose a bit with it. Just slip it inside and was thinking this might make it more uniform across the fire-hose as far as being flatter.

Has anyone tried this before? Figured if I used something very flexible like cotton material it should still be able to move easy. Didn't want to put anything hard on the insides. Comments?
