Re: spare foam -- Around here, we call it "pluck-foam" -- squares of foam ripped out of those foam-lined trays and cases used for storing minis. (You just *pluck* out the squares of foam as needed to make space for a place for your miniatures to nestle in.) I use bags of the stuff as packing filler, but also sometimes I'll use craft glue (regular white glue or Tacky Glue) to glue it down to cardboard/foam-core trays to cushion terrain boards in storage. But, hey, I've got so much spare, having another use (speckling paint texture!) is certainly welcome. :)
