Well, I didn't get to sampling yesterday. Here's what I did do:
I guess it's a question of approach. My basic training is in science, so before I set up my experiment--sampling--I wanted to test my theory on paper. I'm planning to make a double-weave tube. My goal is for the folds between the two layers to flow seamlessly. So I spent several hours yesterday with pencil and paper drafting out the weave structures for my top and bottom layers and checking how they interact. I think I've got it. Now it's time to test my hypothesis on the loom.
