How shall I groom thee, eyebrows? Let me count the ways...

I'm sure there are others out there who can sympathize with me--I have the worst combination for eyebrows. They are 1) sparse, and 2) not well shaped. This generally involves me having to 1) fill them in everyday, and 2) pluck.

An old rare picture of me without makeup. Where are my eyebrows??

I hate plucking. It hurts, and it leaves my brow red for at least an hour (sensitive skin much?). Worst of all, it never seems to last very long. I refuse to wax, because um, hot wax near my eyeballs? NO SCHPANK YOU. My other alternative is threading. Not familiar?

It is apparently an ancient Indian technique that involves using thread (as in the kind you sew with) to remove lines or hair or individual hairs from the brow. It looks kind of cool, and far less painful than either waxing or plucking. AND in most salons, it will only run about $10-15.

Concerns? It seems like it removes the hair at the surface of the skin, akin to shaving. Which makes me wonder how often you would have to get your eyebrows threaded...$10 isn't a lot, but it sure could add up. There are also video tutorials demonstrating home threading, but I don't trust myself that much. I'd likely take all my eyelashes out accidentally.

Has anyone tried threading before? Thoughts?
