I should note that the threads and paints I used didn't produce all the color effects I was hoping for, so I gave up on any scientific accuracy and just had fun.
I enjoyed working on this, and you can read more about the exact materials I used at my home blog, www.textileranger.com . That is a WordPress blog and it has a great "image compare" feature with a slider, and I think it's a better way to view these pictures, so I hope you drop by!
