I been hunting around the boards here (and
a few other sites) to see how marshes are made and in most cases all I come across are areas of scatter material (often on CDs) where the grass area is built up with putty / foam and the base becomes the bottom of the water.
I'm currently looking at a small board (along the lines of my ice board) and wondered about the following method:
1) Push random holes in thin cork roll (approx 2.4mm thick)
2) Paint the board as water - just where the holes would be is an option
3) Stick the cork down as the playing surface
4) Paint the cork and flock it
My initial thoughts are the main marsh will be flat (not too much of an issue on a 2x2 board) and the paint / flock may go into the water. Other consideration is that the edge of the land / water will be a step and not a slope - maybe a bit of filler / green stuff to handle this?
