This gave me the idea, why not build a multi stone pond box
out of teak or Ipe? Something a bit heavy that would stay put,
T&G joinery, dovetail corners, brass screw clamping for the
stones, and you could use a waterproof poly glue or some such...
I think I might do this when I get into water stones. Currently
scary sharpening myself, but this idea could become a classic.
