Today I took the "foursies" of flannel waste triangles that I put together a few days ago, and I have been seaming away. It is six blocks by nine, so forty intersections to match through the machine. O my gosh, was it really that many? No, it was eighty, two intersections per block.
And here's view of the end result. I decided to set them randomly rather than any of the several "organized" sets that I tried first.
