Very nice start! It will look great when finished. So how many terrain boards you will have in the end? Judging by the sketch in the first post there needs to be quite a many in the end?
I think we are looking for 12ft in total, most of the rest is mats and GW battle boards.
It will all be for a big, sorry, massive and immense charity game, for a little girl who is very poorly.
