Pshop 7 - create custom special effects brush

Greetings! It's been ages upon ages since I've posted here.

I know how to create a custom brush shape, no problem. Is there a way to create a custom effects using your own shape but creating an effect similar to the one you get with the butterfly or flower brush, like this?



This is the result I get when I do my own shapes:



I would like to know if there's a tutorial out there or some easy way to get the sprinkling effect like in the first pic.

Thanks in advance

I think that if you play around with the scattering you will be right on your way...

Thanks, I didn't know the term was "scattering", I did some searching and found some instructions.
