Craft Show, Mostly Bust

I don't know what it is about benefits for animal charities, but nobody buys my stuff. I barely made my expenses, and as it turned out, I need not have bothered with anything other than Ravens & Orioles. Nothing else drew interest at all. Still, I did better than two of my three 'roommates', one had a single sale and the other had none. (The fourth cleaned up. Go figure.) But I met lots of doggies, plus some rats, chinchillas, guinea pigs and bunnies. I had help from my buddies Jim and Jeff, so it was a easy and social occasion if naught else. Trying to decide if I should bother with another show, I need the money but do I need the aggravation?
