I have been doing some design work for a comic company, and wanted something else to break the monotony, so I designed a generic playmat for myself. I have two blank white ones that I want to get done up, but I haven't decided yet what to do with em.

Left side allows you to use counters to keep track of your life and your opponents (99-0). Above is for other counters, such as storm, floating mana etc, or you can use it for RFG stuff. Right hand side is for library and graveyard. I still havent decided if I'm gonna keep the mana symbols.
Cheers,

[edit] Took everyone's advice and tweaked it a bit.
