x2 on this idea
I have to admit, that I am hooked on this stuff. SO not "correct" for my old machines but having a stretchy belt that can be "stitched together instead of using the staple is pretty cool. I have an original Singer treadle belt tool and it is still way easier to use the tubing. (I blame Mizkaki, she started it for me...)
