When I trim I leave 1/4 inch of batting and backing by putting the ruler at 1/2inch mark on the stitching line. The purpose is to get a full binding. I don’t know how that would happen if the quilt is trimmed before the binding is sewn on. I suppose it would work with a narrower binding but I like the 2.5 inch because I can use leftover binding cut into 2.5 inch squares for scrappy quilts.
