Hi David,
Thank you for adding this valuable information to this post. I had never really even thought about protecting the back of the canvas. But, even with something stapled to the backside of the stretcher bars, I'm thinking that still wouldn't prevent those 'square creases' if someone lays another painting on top of one. (Not that it's a problem for me since I don't have anything in a gallery
) Wouldn't there still be air space between the canvas and protective board? Or I am misunderstanding your meaning? But your suggestions would certainly help avoid damage to the canvas from the back.
Oh, and after rereading this before I post it, I came up with another question. Getting back to the original posts, with cardboard or something else against the back of the canvas, aren't we back to not allowing the canvas to 'breathe'? I guess a hole needs to be cut in the cardboard too?
thanks,
Joan
