Place the vinyl over the top of your wrapping paper and voila! A reusable battle map. You can get a roll of 25 feet for like 3 dollars, who knows you probably have some scraps laying around, don't throw them out! On the back it will have cut lines or your grid lines, isn't that awesome? Now you can draw on these if you want and make permanent maps, or you can also get a piece of vinyl from the fabric store a 3 foot by 4 foot square will probably run you 3 to 4 dollars. We are going to use normal cheap wrapping paper. You can buy already pre-made battle maps but those can run 20 to 30 bucks depending on what you buy. You can buy specific dice paper which is tan in color with dark green lines on it, but a role of that can be 8 to 10 bucks, just by itself. They further bring your players into the game and immerse them in the experience that is role playing.
Battle maps are essentially grid lined papers that you can place your miniature characters on which provide for spacial awareness.
