Braybaker

Does anyone know any good tutorials for Braybaker (how to use it) Ive tried it a few times but always get really bad results: e.g- (sorry no pic just now, internet is being slow)
you can see that it is blurry and all over the place.
I really only wanted this for a very small part of the texturing, but it would be nice to know if i could get a better result easily.

thx
