Wargames Terrain Squares

This started out as 15cm (6") squares for grid based games. Then I realised I could build terrain bases for forests etc by using a combination of edge pieces. And I could build amoeba like shapes as bases by joining various curves and corners.

The pieces are to be held together by 3mm cylinder magnets (3mm high x 3mm diameter). The hole is just tight enough that you will need to use pliers to push the magnet in, but no glue is needed. When inserting magnets, make sure the polarity alternates.
