I was asked on Friday if I would consider judging the knitted and crochet entries at the county fair here.
I could do it, the number of entries is not usually terribly large, and I've certainly been doing this stuff long enough. But I have no particular "professional" qualifications. I've only ever taught one class, I don't write on the subject. When I asked "Why me?" the answer was just "Because we talked it over and thought you'd be good."
The judges give written comments on every piece, which I'd be willing to do. It probably takes about half a day, and they pay you $50. (Wow.) I just keep wondering if $50 is worth getting tarred and feathered for. :)
