Have you used the Foldisheet system, as reviewed by Wayne de Wet? What did you think, where did you find it useful? Any issues you think could be addressed by the manufacturers to improve on it?
I can recommend blackout curtain lining, this has a cotton layer on top and a butyl layer underside, it will not let any paint through and is so solid, paint spills will not go through. I bought a cheap roll from a remnants place. It can be cut without fraying and also sewn side to side to make larger sheets. Only downside a little heavy ! Can also be washed (dry cleaned ? ) .Also because of close nit, easy to dust off.
Forgot to say but a very large decorating distributor is selling these blackout sheets of this as dust covers now !
