I finally got my 20 blocks knocked out. Assembly was tough. I don't have the ability to let go, and let things fall where they may. I arranged, and arranged again. On an upside, I didn't press the finished blocks (just the tubes), and all the blocks seams, save one, nested together.
Excuse the un-pressed-ness
It looks a little small, even for a throw, so I think I may add a border, and use the red check for the binding.
