10-4 - but I have to wonder what it would look like 50 years from now. The reason I use clear pine stretchers is to avoid warp - there are also keys that tension the canvas and (I would think but I haven't test it yet) in a few years, due to natural humidity, the canvas will sag and these keys allow you to re-adjust without re-stretching.
Its the reason I use clear pine wood over bass wood .
So cardboard - well, I would think that is just not going to stand the test of time (but I say this without any "scientific" basis - just an opinion). Actually, I have a giant piece of cardboard from my LCD TV - I stuck it up on my windows in the basement to block out the light (my solution to creating a digital darkroom on a budget
) and now, 2 months later, its really warped. Yeah, this is a TV box - maybe it different...Just saying.
The bottom line - I'm selling prints telling people they will last a long time and asking them to pay for something that is quality...and for me, it goes without saying that canvas has to be of good quality, but also have "good bones"....that is again my view of what the market will bare.
Now, final thought: if I was your average do it yourselfer who has "snapshots" of my trip to Alaska taken by me and my spouse and I just want some memories stuck up on the wall, maybe cardboard would be just fine. If the price point is low enough - art can be viewed as disposable .
