Good luck finding the missing walking foot. My walking foot recently "died" and I had to get a replacement. It is really nice to use one that works properly. So, I took the old quilting guide from my old walking foot (that only fits on the walking foot on the right) and took it to work with me. (I work at a vocational school.) One of our instructors converted the old right-hand guide into a left-hand guide that will really help me when quilting a large quilt that has to be rolled up from the right. Does any of this rambling make sense to anyone???? I'm happy, anyway.
