I needn't have worried. The salon was really nice and my stylist was terrific. Basically I sat down and said "I'm tired of having boring hair, I don't look good with short hair, and I've got better things to do in the morning than mess with my hair" and let her go to town.
It's now much shorter than I expected. It's chin-length in front and shorter in back, and angled.
It's taking some getting used to. People seem to like it, and one person pronounced it "sassy," which is exactly what I need right now.
