So everyone has the space or time to build a full out warhammer table, this might be because you are in an appartment, or you only play at school. Regardless, this is a quick video giving a quick explaination of how we go about making our battlemats for the local club. These work great because all you need is two of the folding buffet tables, and you can set up your mat.
In our case, we rent a lunch room at the local College, so we don't have to worry about tables. They have plenty of the 8 x 2.5 foot buffet tables so we push them together and ig gives us an 8 x 5 space. So to get a proper sized battlefield, we build a battlemat and lay it down on the table, it works great.
Take a look at the video, and enjoy.
