While preparing for my upcoming play test, I made a map of the level that I can show the players. Instead of re-drawing the whole thing by hand, or scanning and printing to make a GM copy, I used a sheet protector. I put the map in a sheet protector and I have pens with Red, Blue, and Green ink that I can make GM notes.
So at the table, I can take it out of the sheet protector to show the players, and put it back to see where things are for the GM.
I have to make sure and line it up correctly so I don’t enact a location base encounter at the wrong time. This is not hard to do.
Since the sheet protector is two-sided, I can put another area in, or draw it on the back of the same page as the other map, and get use of the entire thing.
The drawbacks are that I can’t use this sheet protector for anything else if I mark it with permanent ink. I’m not worried, this sheet protector is probably 25 years old. I bought a pack of 100 sheet protectors on sale for about $7.00 a couple months ago, so I’m not worried about running out.
This old sheet protector does not seem like it would work with a dry erase marker. It is different than my other old sheet protectors. Because it is so old, I didn’t even worry about making permanent marks on it.
Sharpies or other permanent markers could also be used.
So there you have an old school way of doing it. If you didn’t have easy access to a copy machine or nowadays if you don’t have easy access to a scanner, you can make one map do the work of two.
This came to mind as I was in my mapping groove. Not the quality of all the great cartographers online. But I didn’t want to have to get up, come in the office, and scan the map as I made various degrees of changes. I have a U-shaped configuration of tables set up with all the gaming materials, and the sheet protectors were right there, along with all my colored pens.
I still had to scan my maps so I can use them online. I can print out extra copies, or backup copies, or a physical copy I can mark up or modify.
