One step along the path so far has been to work with a PP that is striped with multiple patterns & has somewhat subdued colors.
For the stamp I used one Jan rak'd me--a moth with minimal details.
Things I'm finding...
Ink colors aside, how transparent the ink is is important--if I want the patterns to show. If the link's too solid, i use the generations techniques to achieve greater transparency.
I also find that--regardless of pattern type--how i orient my stamp on the pattern greatly effects the end result.
1st pic is of the PP.
2nd is the moths in various directions on the patterns.
Ink used is pigment in a verdegris color. Some images are 1st generation & some are 2nd.
