I've just started the Padding Canvasses video and I'm a bit confused with the positioning of hair cloth on body canvas. In the Cutting the Canvas Video, Rory says to cut the hair cloth about 1/2" above the shoulder but in the Padding Canvas video he places the hair cloth 1" down from the shoulder seam. In the Padding Canvasses video this results in the hair cloth ending just above the notch. When I place the hair cloth like this, it ends up below the notch. Should the hair cloth have shrunk when I soaked it, or can I just trim it so that it doesn't go down as far?
