The best thing to do if you want some arch in your eyebrows is to:
1.) have it done professionally to your liking
2.) Buy a white eyeliner pencil
As the hair starts to grow back in, take the white eyeline pencil and "draw" out the shape of your eyebrow. Then, pluck any hairs that are below the white lines.
I have been doing my own eyebrows for years and this is how I started off. Now, I just "freehand" it and don't use the white eyeliner.
