Right this will either hang on a wall or sit in a little stand, the kind used for plates and such. I'm sure you could use any kind of canvas, in fact the ones that are stretched canvas on a wood frame might be even better, they could stand on their own and would be easier to hang.
I guess the thing is to be sure you get that paper stuck on really well and that small canvas board needs some heavy duty adhesive. They had a glue there for us to use, of course, it was the "super duper" glue that they sell. LOL!
I think they could make some really cute pieces to hang on the wall and the dimension would be pretty neat. You could do some really cool things with those canvases. I used ink to color the edges of the canvas, but you could use paint instead if you wanted.
Using canvases must be the rage now, there were a few booths that had projects and displays that used artist canvases.
If you do use them for a project or two, please do post them. I'd love to see what you do.
