Familiar Double Pawn Bases
Out of sight, out of mind, that's often the problem with familiars. These specialty pawn bases have two slots, one for a character, and another for a small companion, so that they're seen and remembered while you're moving the pawns around.
These bases have sockets in the bottom to make them compatible with my flying pawn base system, found here: Variable Height Flying Pawn Bases
(I started by modifying the wonderful Pawn Base from Mapembert)
