Excellent suggestion. I hadn't thought of a 90 degree join. And I think you're right about the 2.5 inch loss at each seam if doing a diagonal join, though I would think it would be a total of 5 inches for each seam -- 2.5 inches for each of the two ends joined. (Does that make sense??) And thank you, cashs_mom for the binding calculator link. Very helpful!
