My favorite item to make is hand embroidered baby quilts. I'm often asked what I would take for it, and I tell them I only give them away because no one would pay what they are worth. By giving them to someone, I don't get disappointed.
I recently turned 2 of my fabric bowls I make into gift baskets and put into silent auctions. They brought less than the bowl alone was worth.
I find it easier to just donate money and give away my things when I want.
