Yea, my lines are kind of fat, I can do thin, but Im not as much of a fan of the tiny lines, so I dont do many. As a starter brush, nothing beats a Mack 00. You can pull whatever size lines you want, its great in the curves. An all around good brush.
The line thickness is all a matter of how much pressure applied to the brush, angle of application, stuff like that. Once you get used to it it just becomes second nature.
And yes, if you Paypal me the money I will pick up all the stuff you need and send it to you.
Feel free to ask if you have any more questions!
