that's staggering good
... but all your stuff is!
* - having now read your blogpost - with all the other great pics, my unasked question has been answered -Cigar Box mat.
styrofoam 'inserts' work well - I tried that during my dalliance with mouse-pad material mats (also tried jam jar lids etc), but your mat is much larger which probably helps.
is it mouse-pad or cloth?
the game set-up / narrative sounds fantastic.
said it before, but your games are absolutely what I'd have liked to achieve in terms of skirmish / RPG (lite). More lucky players at the Con.
