bonsai shelves in the garden

First ever bonsai shelves in my garden since we moved in back in autumn 2008.
You see, I'm just an amateur :-). Some more shelving to do, and then I'll add a few trunk logs to put some more trees on. Limited space available in my limited garden, for proper presentation.
I perhaps like the growing field and the little corners here and there more, where everything is growing and still 'becoming'. But, my wife is happy the garden table is now free of trees and spoiled substrate.
