Echo Weave is on my bucket list!
I am just now trying to research it. The color interaction is just about enough to make you say "Aaaaaahh" all day long! I have found where a Max Hailperin has called it "corkscrewed network twill" and when he used 8 shaft he called it "8 shaft polychrome corkscrewed network twill." There has been some exciting things made by Alice Schlein and Bonnie Inouye too. Marian Stubenitsky has a book I am just now reading called "Weaving with Echo and Iris"
