Pimp my chair

This weekend we did some yardwork and de-cluttering and made a trip to the dump.  When we drove past the furniture pile at the dump, a pillar of light shone down on this chair.  Now, this may look like junk to some but to me, it has great potential so I took it home.  I had my daughter try it out that night in some pics and I think it will rock for portraits!  (I love the headshot of my daughter.  I was squealing with delight when I looked at the back of my camera).

Here's where I need your help.  The seat cover obviously needs some help.  What would you do to this?? What kind of fabric could I use to cover it with?  I need your help to make it FABULOUS!
