That might be expensive for a single (or few time) use map. My suggestion, print it the size you want using poserazor http://posterazor.sourceforge.net/ or MS excel to print it into a few sheets... once you've put it all together, laminate it for the best look and making it dry erase friendly for many uses before it starts to stain.
Alternatives to lamination if you don't have access or the map is too big, is getting rolls of self laminating (wallmart and staples has them) that stuff is tricky to get bubbles out at times. A last ditch would be to get a clear plastic table cover, that is also dry eraser friendly, you can just put any map under it... that would be a great solution if the map is a one off and you don't need to keep the markings for another day.
This may be incredibly dumb and I apologize if it is, I’m new to this. Does the cover get in the way or need to be like folded back? Like I said, all I could find on Amazon where notebooks like this one: https://www.amazon.com/dp/1976258731/ref=cm_sw_r_cp_api_i_94.OCbF1WJVC9 The cover is kind of a pain in the ass to weight or hold down while drawing.
Thanks! Yeah, they had a good time working their way through it.
I looked everywhere for a notebook like that, ended up ordering it off Amazon.
