This links to a tutorial for 'seat sacks' that hold papers & books on the back of a seat - but I also LOVE the curtain rod with chalkboard pails for organizing art supplies! Love this for a kids homework table!
Designate a spot in your home where your kids can hang the art they create. It's much better to display their art than to piling it in a drawer or in a cabinet. And think to rotate the piece of art regularly. Your kids will be proud displayed artists!
