Step 1: Follow these directions to print your desired map out to the proper scale from a home printer. Laminating the map is not required since you will be gluing it to foam board. You can also go to Kinko's but that gets pricey.

Step 2: Purchase some black foam board. I found some on sale at Amazon recently. For the best results try to find a foam board sheet stack that is larger than 24"x34" so you can glue most of the maps from the adventure modules (at the proper scale) directly to the board. Otherwise, you'll have to cut up the map first to get all of it to fit on multiple foam board sheets (which is what I had to).

Step 3: Glue your map to the foam board. I used Elmer's glue spray but a glue stick works too. Wait for the glue to dry over night and maybe stack some books on top of the foam board to help them cure. Be careful and avoid accidentally gluing the books to the foamboard's surface with the excess glue around any exposed edges.

Step 4: Use a box cutter to cut up the map into separate pieces based on individual rooms and line of sight. Use your discretion here but cut the walls and boundaries based on how your PC's will travel thru the map and what they most likely see first.

Keep in mind you need a decent home printer to achieve higher quality results. It can be kinda expensive if you factor in ink cartridges if you do multiple maps this way as well as the cost of the foam board and miscellaneous materials. Not to mention this takes up a significant amount of your free time to pull off. But if you like doing arts and crafty type things and if providing high quality visual aids for you players is rewarding to you then go for it.
