I wrote an article this month for the Contessa Blog! Check it out– it’s Stocking Stuffers for Game Masters.
My criteria included that it had to be useful for GMs, be inexpensive, and fit in a Christmas stocking (a lot of stuff is useful, but doesn’t fit in a stocking). You won’t find $35 dry erase notebooks or Dwarf Forge terrain. Nope– these are for the GM who sits down every week to run a game and goes through 10 index cards a week, three dry erase pens a month, and loses monster miniatures so often, you might think she’s eating them.
