definately trogdor!
The way I understood the feathering was this:
Once you have finished with a new highlighting layer, take a damp brush and \'pull\' slightly down through still wet layer into the darker layer that you are working over. You don\'t want any fresh paint, but rather the dampness of the brush will lightly move some of the newest layer around.
The idea being that once dry the transition line where the two layers meet will be very smooth and soft, instead of a hard edge.
So in answer to your question, I think you want to have \'blurry\' lines....
Hopefully somebody can explain it more concisely than that....
