Fastback rear speaker boxes

I finally got speaker boxes made. Now I'm looking for different ideas in what to cover them in. Anyone got pics of speaker boxes and material they used?
Thanks
I would think any porous fabric would work. We have a fabric store that has tons of choices. Just think about what covers some good old fashioned house speakers. Gall dang technology is changing so fast when it comes to speaker technology. Glad to see you moving forward.
