I agree. When I pinch tested my vintage sports coat, I actually was able to peel off the outer fabric from the front and back of the canvas which created that fabric separation sound. It was pretty addicting to listen. I actually started doing that on all of my sports coat just to hear that sound. lol

If on the other hand, you can rub the fabric against itself, there is no fusing.
Half canvas is supposed to be glued on the bottom half and stitched on the top half. Don't have any pieces in front of me, but IIRC, the same rules apply and you can feel the fusing down at the bottom.
