I've sold in shows and to friends and colleagues, but never on a website. I have "stuff" for sale on my zenfolio site with pricing described on another page because I, too, would like to know what a client would be interested in. I also have "stuff" on The Artrepreneur website, but have not sold anything; a couple of artists there have told me they had the same experience and removed their work from the site. I am about at that point. Like Rob intimated, I do it for the joy of creating, but it would be nice to sell occasionally online. There's always the possibility that perhaps I'm not good enough, but I don't think that's the case with you, Peter. Good luck. If you learn something, please let us all know!
