I probably don't understand as much as I thought I knew a couple of hours ago <g>.
I am looking at the picture, and I am thinking ... if I were going to see if there was an angle on that ruler that woud fit that design, I should be able to lay the ANGLED line on one side of the diamond, slide it down to the point, and where the angled line intersects with the straight line, that is my degree ....
I'm not sure that if you put the straight line through the middle of the diamond, you could check the angle ...
but, then ... I am old ... I may not have grasped the main idea of your original question.
I don't know how much fabric you have, but I am thinking - - maybe, cut it in strips, a quarter inch from a line of diamonds ... an extra thread here and there, and it should look like the lone star block you are after.
