I agree with the previous 'posters'. I am happy to say that sometimes I realize by looking at the pieces hanging around that I have grown as an artist and I can no longer look at the work that is 'less than', but I know someone might be happy to get it for a buck or two so I donate to Goodwill nearby.
Or if I know the piece is good, I just leave it in my online gallery and like this week-a piece that has been hanging around for a year or so, sold out of the blue. Ya just never know.
And not very long ago, an artist I admire very much messaged me and asked for my address, then sent me a great 8"x8" for free that she had done which hadn't sold after a year! I was very glad to have it!
