Suggestions on recovering Deluxe Room Tune

My cat decided the Room Tune was a nice scratching post, and although he didn't damage it, it looks a bit threadbare. Any suggestions of recovering -- where to get fabric, etc? Thanks.
Most any hobby / craft store will have various materials. If you want something that is quite rugged yet inexpensive, you can usually find burlap in black or brown. This works quite well and isn't reflective at higher frequencies. Be careful of using "fancy" materials that are very smooth and or shiny / glossy as they will not work as well at higher frequencies.
