The mat I have used in the game are simple Games Workshop green mats. They are so cheap and good that they decided to retire them from the market!
cheers Stefano
thanks Stefanov...
think I may have made a boo-boo with the 'mat-o-war'... odd - somehow every mat / terrain set-up I see around on the forums is much closer to what I'd like than anything I seem to manage myself !
