Really interesting thread and links! I have been making hand-drawn & hand-reproduced greeting cards for several years, even sell a number of them.
I started drawing people's homes, and making greeting cards of the drawings; next i started drawing and reproducing flowers which are native to this area, and are (at least) equally beautiful to the horticultural ones that take so much hothouse care. (I'm really into valuing what's in our backyard, regardless of where we are- i once wrote a paper on "Useful Plants of Urban Waste Places- i.e. vacant lots).
I have 5 samples at a website called www.sleepingbean.com, under "Native Notes". You can get there thru Megacrawler.
