From Surface Treatment Workshop

Some techniques if not persued further look like just old grunge.
The pulled paper technique in Surface Treatment Workshop is really just a step to your finished piece not your finished piece as most of the techniques are. It is the layering of images and surface techniques that make a piece interesting.

The top example is what was done with the pulled paper/wet gel transfer technique and the second is what it could become when it is pushed further with drawings, collage and paint. I personally love that in and out of focus thing that is happening.
