I know someone will have answers to my questions. I have this Singer 08/28. I think I got it in 1982. I have most of the accessories that came with it. I quess I do not have the Snap-In Feed Cover. Know where I may be able to purchase one? Or will something else work to cover the feed dogs? Also, is there a screw on 1/4 inch foot I could get for this machine? I have a seam guide but it goes from 1/2 inch to 1 1/4 inch. Haven't been quilting that long so a new machine is not in the cards right now.
