I'll see about posting the way I do tri-recs. I do have the rulers and would not want to do without them.
I got all the hourglass blocks sewn and started trimming, then I had to go to work. I looked at the posted directions and had a "what the . . . " so I gave that up and sewed them they way I normally do. And since I'm gong scrappy, methods that are designed to make more than one at a time aren't going to work for me anyway.
