well, doc, i tried it. the sale at the virginia arboretum is happening this weekend. i used your suggestion and not only darkened the signature i had carved into the bottom of the pots but added with a sharpie "Original Art". the two large most expensive pots sold first to a single buyer and others went off with new owners all day. maybe tomorrow they will all be gone.
and the other idea that if something sells fast, raise the price. yep, that will be done when i offer the big ones again.
If you weren't female, the next step I would suggest would be wearing a large codpiece."
