My son makes at least one art project at school everyday and so we decided to come up with a way to display them. I ended up just stringing some twine on an empty wall in his room.
He has made a lot of projects since September and his display area was full, so we took all the projects down and took pictures of them and then I created a collage in Picasa. See how to do that here. In January, when I make our 2011 scrapbook, I'll insert the collage picture, so we can always remember his fun art projects on one page instead of 36 pages.
