BattleBoards is one of the very few professional gaming terrain board makers in the world. They have made numerous gaming/display boards for manufactures and clubs to be exhibited at Salute in London. They have recently begun posting videos of their work on youtube. I have posted all the videos for their latest project WW2 Bolt Action Italy board here for your enjoyment. All though this is very advanced stuff, if you watch carefully you should be able to pick up some tips to use yourself no matter your personal level of terrain making.
