I have a confession to make, I did buy the fish and the lilies, or at least my daughter got them for my birthday at my request. Koi are considered auspicious by the Chinese. The rest consisted of an old plate, the usual grout, and some slate tiles that I just happen to have jostling for position with all the other accumlated stuff in my place. I could have put the tiles closer but I wanted them to be firmly grouted and the surface of the plate was shiny.
