I have always tweezed my own eyebrows, as far back as I can remember. I would say probably 13 years old i started, and the first time I did them was terrible. One turned out great, the other, terrible. It was like 2 hairs thick only, and i looked like I had a Whoopi Goldberg goin on above my one eye lol.
Now I am confident in my tweezing skills. I have waxed myself a couple of times, but I am so scared I am gonna put a huge glob of wax on and lose my whole eyebrow.
