I found this idea in Family Fun Magazine awhile ago and am just getting around to doing it.
It is art gallery for the kids artwork. I put in down in the "Kid zone" where the walls were pretty bare.(except in my craft corner where there is a multitude of stuff hung randomly around)
These are just some frames painted after removing the backs and glass. Then just stick them on the wall with some clips which makes it easy to rotate the artwork. I got the frames at the dollar store so the whole project was cheap. I added the photos of the "featured artists" for fun. Just one way to encourage the kids to be creative and to let them know that what they create is important.
