the rules support section of the website contains hex grids which you can use to plan your layout using the terrain features available. At the club we often ask a non playing member to choose and layout terrain features from a limited selection. Players then dice for choice of table edge and first deployment.
With two players , one could selct and layout the terrain and the other have choice of table edge.
I have a selection of sketches of different terrain layouts on the grid paper which I will scan and upload as examples.
