Two blocks made me realize that I didn't like my scrappy choices at the block intersections and it would make more sense to just make full hourglasses instead of flying geese units if this were in a quilt with the same blocks. And, I had to check why the "no waste" flying geese had lots of room to trim. (I failed to read "finished" and assumed unfinished size). More units were made to check the math again and I decided that it had to be a usable size.
Now I have the pieces for a 2.5 x 3 block layout (40x48" approximately if my math is better than it was yesterday). I might have sewed parts of the top together tonight if my helper hadn't helped me layout pieces by walking over all of the ones already down to trade out squares. I am debating leaving it on the floor tonight to see if I can put it together in the morning. It will probably become a dance floor shortly after the helpers wake up. Guess it is lucky that I'm not committed to the specific layout.
