I have been looking on newegg for those big @ss mouse pads. As I was browsing, it came across to me that you could probably easily make one with a trip to a hobby store. Does anyone know what material is used to make these large mouse pads? I want something that will take up about half of my desk. Probably about 24 inches across and 12 inches wide. So, what material should I use and has anyone ever done a DIY mouse pad?
