Question:

What kind of stencils and patterning techniques does HR Giger use?

I know he uses some stencils in his airbrush work, and I'm just wondering if anyone knows how he made them and/or how he uses them and and his patterning techniques in general.

On his website he seems to describe his technique and materials. Go to the database section.
