This is as far as I got when I put it away last night.   About halfway along the top gray edge is a small bobby pin (you can see it pointing up-and-right) that I inserted when I started yesterday.  So I managed to do several inches along that side.  I’m not thrilled with how the double corner at the right turned out, but i’m not going to go back and ‘fix’ it.  It is what it is.  I’m also not entirely thrilled with the joining method I’m using, but it still looks better than following the instructions in the pattern.
