I know what you mean. Last year I answered a call to artists in Reno and created a block print for the show. I delivered the framed print and went back for the show/auction to find that they'd canceled. Oh, yea, there was an entry fee. So I asked for all of it back and have never worked with them again! But not everyone is like that. Feats of Clay probably has an entry fee, but you have a chance to sell your work at the show. It always blows me away how little ceramicists ask for their work. But sculpture, like yours, put a high price on it and it will sell.
