Serendipity really. I recently bought some OSB for some non-wargaming projects. Having cut 1 piece down to 6'x4', tested the footprint and functionality, the project was unanimously cancelled. Well, it never hurts to have spare materials hanging around but it suddenly hit me that I've been itching to extend my table to 6'x4' again and make it it sturdier. Serendipity!
My latest experiments with a gridded table have finally failed beyond redemption. I can see some of the attractions, especially for a small, sit-down, cardtable sort of game but over all, the minuses equal the positives and its not my style. So, I tore down my flimsy patchwork table and replaced it with a more solid one piece of OSB then painted it.
Now to test it!
