Classroom Set-up! (covering up ugly walls!)

In my new classroom, I have one of those accordion walls.  It was dirty, grimey, ugly and distracting!  Go to your local dollar store, get 4-5 cheap tablecloths and cover it up!  Here is what I did with an Easter yellowish color tablecloth ( wish I did purple or blue!)  I simply used thumb tacks on the wall to hold them up!  Easy put up, easy take down, nicer looking class :-)
