I would just like to suggest that regarding the Project Eternity mousepads, would it be possible to get them done by one of the gaming mouse manufacturing companies rather than an 'office supplies' company.
I play competitive FPS games and your standard office mousepad doesn't offer much space and generally do not last very long and don't use the best cloth. They tend to wear down very fast.
Razer offer smallish size mousepads such as this one on their Goliathus pad, which is a good pad that tends to last a while (unless you spill something on it).
Puretrak or Steelseries (the QcK) would be another option.
