I finally got back into the studio to sew some dark blue scraps together into slabs.
I cut a few triangles, and had an epiphany. Can you see the middle triangle in the bottom row? See how the strips are not lined up at right angles? I was moving the template around and I saw that and thought -- HEY! Why not? I'm going to make more like that.
I already know I'm going to use this layout for these dark triangles. I'll also include some purple.
