I'm worried about the thickness of the quilt not being taken into account. I will have to do some test pieces.
What I have done instead of trimming is *mark* the cutting edge with a permanent Sharpie. This is how I square up the quilt, and the line becomes a "virtual" cutting line for lining up the raw edges of the binding. I then trim the quilt to the binding edge after the binding is sewn on.
Sometimes I machine baste just inside the drawn line, then trim to the line before sewing on the binding.
