So I made some, put it away, made some, put it away....and neglected to take notes on how I needed to trim the squares. Now three of them so far are about 3/4" too big. Those I will be ripping apart, trimming and reassembling probably last thing. But this time I was smart enough to write down a note about trimming those pieces and put it in the box for next time.
Nice, but WRONG by 3/4"
But here's what I have so far. I think there are 25 or 30 total that need to be done.
I'll finish the rest one of these days.
