Ideas for Displaying Children's Artwork

I found this post about Top 5 ideas for displaying kid's artwork.  I was wondering how other art teachers and parents put their children's artwork on display and celebrate their creativity?

I often use small 4'X6" or 5"X7" frames, which often can be found for just a few dollars, to highlight a favorite part of a child's piece of artwork.

I also love the look of having student's work displayed on a clothesline.  So simple to make and easy to change the display!
