anyways, I'm attempting to create my own pattern layers for use (digitally, of course) in shading and was wondering if or how anyone here has re-created the effect and would you be willing to post examples,and maybe how you did it (if you like)?

:)  when done properly it really has a mesmerizing effect.. almost hypnotic.

that's interesting and it looks great!  I haven't tried a half-tone screen yet---

I did find a way to make a crosshatch effect that works well, (although just a little bit tedious) but I'm finding I don't really know when is too much and exactly where it should be applied!!  :D  I'd post an example but my art doesn't look very good next to yours (haha).

I've been looking through some old comics from the 80's and I'm seeing alot of different patterned textures that are very subtle but that look awesome-- so funny how you see things you don't notice.
