baskets4moo: thanks for the pictures. I like the idea of a bag for the foot as mine seems to be too tightly squeezed on the end to fit in the tray.
tartan: I really like the idea of putting the cover under the pressure foot, I haven't thought or heard of that idea. I actually have plans to make a bag and sleeve but am waiting for a merchant to come up from Yuma with a leather needle as I decided I would like leather on the bottom so I can set it down when taking it to classes.
