Heya,
I never did threading. Your brows grow just like all the other hair, so if you get threaded, you'll have to pay for it regularly.
Here's the home way to do it:
1. First trim the brows. I found it pretty difficult to shape when my brows were big and "caterpillar"-like. This first step takes you from the "bushy 3-demensional" look to the "sleek against the skin" look.
There are guides online on how to do it, but basically, you take a comb and put it over your brow, and you use small scissors to trim any brow hair that sticks through the comb. This makes the brow hairs shorter, and most importantly even length. Gotta be careful not to cut too much.
2. The arc shape (assuming you're going for girl, not drag queen) has some basic principles that lots of websites use:
3. Carefully pluck to the desired shape. The important rule is don't overdo it. Sometimes removing one or two too many hairs can ruin the clean line, or create a "hole" in your brow. This is especially true at the outer edges; your brow may be only 2 or 3 hairs thin. Also remember that if you do the ultra-thin brow look, you may appear odd in male-mode. In my case I went for a slightly thicker, but still sleek shape. The good news is, fuller brows are back in fashion - just look at Cara Delevingne!
4. If your brows are still faint / uneven, you can use some eyebrow pencil on them as part of your makeup routine. You have to be really, really gentle here or you'll end up looking like a 3 year old drew with on you with crayon. When I first started doing makeup I used too much and too dark eyebrow pencil, I toned it down over time. This girl is very subtle:
5. Maintain the look by plucking the hairs as they pop up again, and trim the overall brows once in a while. It'll never be as difficult as the first time though.
