his idea can be expanded upon and tweaked to your liking. Use Maize Noce or Terracotta or mix them. Use 1 liner, 2 or as many as you like. Surround 1, 4, 9, or even 16 tiles in a module. Insert what ever you would like at the junctions, Wood, Metal, Glass or our favorite, TILE. The liners need not be tile.(Bad idea) but who know try wood or what ever. With our base tile as your anchor you cannot make a mistake.
