What is an 'Artist's board?

To the artists out there, what is a good pin board surface?

• I am looking for big white panels on which I can pin images, and I'd like the surface to be as smooth as possible. I think artists sometimes pin their drawings or photographs up on their walls, they must have some sort of soft board surface, anyone can help with possible ideas? I am not sure what the name could be for this, if I google pinboard I can only find office bulletin board websites, and they are either made of felt, magnetic boards or cork, which is not what I am looking for.

• Answer:

  foam like there white or black staples has um or office max so look foam you can get big on or project ones like class project size good luck bub101
