I agree with prism. I have the extension thingy for my machine, and as far as I'm concerned it's worthless. I made a "quilting" table out of same size cardboard boxes covering my entire quilting table, covered with the heavy clear vinyl from JoAnn's or Hancock's, which is taped on the bottom, and made a spot on the end for my machine, when it's not in use, it's standing on edge against the wall. I also spray some fabric safe silicone spray on the vinyl and the machine bed, it's really amazing in the difference it makes.
