I used archival ink and colored it with my purple spectrum noir marker. I should have photographed against a colored background in hindsight! I love how my eye segments the white soaces between the zig zags a different way each time I look at it!
I have got a bit behind!
I would never have thought to put blue with brown but it was someone's brainwave!
The colors look so good together I'm going to do combine them more often!
