From my last post, I build a second half of my 3' by 3' modular table using an identical technique: a 2' by 4' piece of MDF board cut into sections, painted, covered with grass paper, and then assembled. I made a slight variation in the layout for diversity's sake.
When the two pieces are put together, they make a variety of permutations.
Now I could stop here (and may take a little break for a few days) but I've been considering adding additional detail: sidewalks, etc. What do you think?
