I hate to steal this thread, but my sewing machine is running out

, it's the same sorta subject, and I can't think of a better place to ask this...
I know that during character creation you can only take a maximum of 6 qualities and you can't gain more than 25 net karma from taking negative qualities, but what do you pay for positive qualities with? Do you get a certain karma amount of qualities for free? Do you have to pay for them by balancing the positive qualities with negative qualities? or Do you have to pay for them with your bonus karma?
At first I thought they were paid for using the 50 bonus karma you get at character creation, but then I noticed that you don't get the bonus karma until the step after you pick the qualities and I remember reading on here somewhere that you're not supposed to go out of order with the steps during character creation.
