This is what I would do also. Use Timtex or Peltex (thick, heavy interfacing). You would basically construct an entire bag, slightly smaller, with the lining fabric onthe inside & the interfacing on the outside. Drop it in your bag and stitch the top of the lining to the inside top of your bag. I'm wondering if the canvas was laundered first to remove sizing to enable the photo to be printed on the fabric.
