Map making

I've been thinking about maps and stuff, and thinking that I should get out the rolls of map making paper that I have and start charting out the maps for the mines and Shade's Castle on the map paper. I picked up some really nifty paper a few years ago for making maps on. It's got this rough textured surface for drawing or painting with water colors on it, and rough edges on it. Big sheets, think they are about 2' x 3' in size. They are great looking things for making fantasy world maps on, and I have been saving them for a time when I am feeling artistic enough to do the maps justice.
