I spent 2 days (and most of the nights too) mucking about with CorelDraw, hex templates and world maps.
Utterly frustrating and pointless; so time for a decision.
I will use commercially available game maps for my campaign planning and to kick it off I hauled out my old Avalon Hill 3rd Reich, spent 30 minutes reminiscing and ruminating, then downloaded a Vassal game box and voila! I have a map of the Western, Eastern and Mediterranean theaters.
Details are scanty on the map but easy peasy to fill in.
Time to move along now...
