Using a square brush

[Sharkcellar]

I've noticed that some artists are seemingly using a square brush instead of a round brush to paint with. I'm interested in trying this out. I've made a square brush and set its angle jitter to direction under shape dynamics, I've cranked the spacing all of the way down to 1, and set the opacity jitter to pen pressure. This seems to be what these artists are using, it's just that I'm noticing a nasty jaggedy edge on some of the strokes at the very beginning. Is this just the way it is and one just gets used to it and learn to hide it or am I going about using the square brush technique all wrong?

This is the look I'm trying to emulate...

That problem comes from setting the angle jitter to direction, set it to initial direction instead and your brush should be good to go.

SouMeng,

Thanks! I figured it out.
