Buy a chair cover that's meant to cover the chair ($10 at Ikea!!) and tear it apart!
Use the torn-up "pattern" to create new covers - the only tricky party is making sure you go with the pattern of the fabric, if there is one (ours was trees so it was noticeable!)
Pin it together wrong sides together on the chair to be certain everything is lined up properly.
I painted the walls dark gray and we'll be adding some shelves and pictures, and this room is DONE!!
