The Very Model of A Modern Wargame General

 The modern table continues to take shape.

A bit of screen, a bit of scrap wood, and a bit of sand...

And you've got some nice tall fences.

I'm not crazy about these fences.  I should have oriented the screen diagonally to make a diamond pattern, and the cloth style screening is pretty flimsy.  If you make these, go with the wire screen for better rigidity and robustness during storage.  Also, I cut the popsicle sticks in half thinking to save space, and now they aren't as stable as they could be.

You can see the half-sticks better here:

The brown lumps will automagically turn into a lumber pile and a stack of 8-inch diameter PVC pipes once they have a little paint on them.

Also added two lengths of rough board fencing to the table.  That's a pretty good start.
