So, I did a bit of snooping and found some great ways to display children's art work. Some could be both fun for the parents and children.
One of the simplest and fastest ways to save kid's art work is in a 3-ring binder. Maybe most of you already do this. I can definitely see myself doing something like this and leaving it on the coffee table for guest to view. If the art work is too small it could be matted on black paper and put into the binder. It's a great archival system/ brag book.
Or after matting the art work to the black paper, it could be hung on a designated wall in the house. A hallway is always a great spot. By mounting them to black paper it gives the art display a cohesive look and helps show off the artistic productions of our small loved ones better than just the wall itself.
I really like both of these ideas because when it comes to actually hanging the art work up, your children could do it themselves. The first example uses a magnetic system with clips while the one following is a curtain wire system. Something like this can be found at Ikea for cheap!
One last idea. Take photos of the art work and collect in a photo album.
There may never be an absoulte solution for this problem, (though it isn't the worst problem to have, right Chris?) but maybe this will help for the time being!
