Displaying kids artwork

I have been trying to find ways to display my kids' artwork in our playroom.  I saw some ideas on pinterest and decided to one a try.  I really like the idea of framing corkboard.  I can change out the artwork as often as I want and make the frames bright and cheerful

I ended up buying 4 unfinished 16 x 20 frames from Michaels paint, and 4 16x20 unframed corkboards (also found at Michaels).  This was so easy, even I could do it without screwing it up!  I painted the frames orange, purple, green, and blue.  Once we move, I will put them together and hang them on the wall in our playroom to display the kids' artwork.
