I pluck/tweeze. I have been complimented on my eyebrows au naturale many times, but I literally just started plucking last month (grin).....my only problem is that I have small eyes, a bestbud convinced me to pluck because if they were a bit thinner my eyes would stand out more. I used to dislike the idea of messing with my eyebrows at all...I was afraid I'd mess them up. I got a brief tutorial and they do look more defined and "neat" when I pluck them. My gurl plucked my eyebrows for me, I was like, "ow. ow. ow!" hah...but when I do it myself it doesn't hurt because I do them tediously, one hair at a time. She is/was used to it so she can handle more "tweeze"...hah!
They are naturally well-shaped I am told but a bit thick in the middle of the eyebrow...I never liked that much. the middle of my eyebrow actually gets stray hairs that stick up if I rub my eyes..dangit! I am better off to tweeze. : D
