Drawspace lesson L02: How to crosshatch with graduations?

In other words: how to create a graduated cross-hatched shading?

This is the exercise from lesson L02.

All the slots were made with several layers. It was pretty difficult for some reason, but it might be because of the paper. At the moment I'm sing a simple 80 gr printing paper. I read that since it's so thin and smooth it can't absorb so much graphite. So I might start using a thicker paper...

Anyways, this is the second part of the exercise.

Again, 80 gr paper, several layers.
That's it.
