I drew my whole yard which is about 3/4 acre at this point. It took 6, or was it 8?, 17" x 11" sheets of graph paper. I got it (mostly) to fit properly where it should be.
What would I change? Well, if I could change life events, there'd be no $30K mountain and we'd still have trees... And if I'd known it would be so hard to find 14' 6" rails, I'd have gone with the standard 10' rails... But mostly, I like the gardens as they are. :))
Life events, sigh! But yes, your place is pretty amazing!
