I am a bit persistent when it comes to something that wants me to fail. I kept trying to figure out how to make eight half square blocks all at once, so I had a fair chance of getting them all about the same size. I finally figured it out.
I was then able to make a modified border around that center portion of the "Union Square" I posted previously. Instead of triangles in the center part of the border, I ended up with just a block. The resultant block pattern is 10 inches square.
After three days of this bugging me to death, I am so very happy it is done, and that it turned out fairly well. Now to figure out what I will do next.
Just a note: This block is square and 10 inches on a side. It's my terrible photography that makes things look lop sided
