Scenic backdrops -- art boards / art supplies?

[RobertInOntario]

Rob:
are you going to paint your own or glue on a printed backscene?
Most of mine are on foamcore, but I find that they tend to warp a bit for some reason. I make them in units and glue bits on behind the joints. I haven't tried the artboard.

Thanks, David. In Photoshop, I merged 3 panoramic shots together (that I took of the Downs in Southern England a few years ago) and I plan to get a photo print made of this. Then I would like to glue it onto the back scene.

The art board -- or illustration board -- is like thick, fairly strong but light cardboard. I could consider foamcore as well.

Cheers, Rob
