I've decided to follow the (many) drawing lessons that are available for free on www.drawspace.com.

There is a problem however: I seem to be unable to smoothly blend shaded area's. There is a pallet knife preset, created by Someonesane, somewhere on the forum (I eventually found it through a Google search); it seems to be the best option at the moment, but it is still not perfect.

I do not want the pencil strokes to be just smudged, or smeared, or blurred, but I'm trying to get the effect talked about in the lessons: to blend the strokes together using a tissue. Could someone point me to the right / best settings of one of the tools to do this? Thanks.
