I have used a regular foot and a walking foot. Either works. I always stitch my quilt layers together close to the edge before I trim the excess backing and batting away. By doing this I have less to keep together when putting my binding on. The stitching doesn't show in the end because it is in the seam allowance.
My question is how do you quilt your quilt without a walking foot? Do you do all free motion? It seems to me there is much more danger of slippage in straight line quilting it than putting on the binding. If you are going to do machine quilting then a walking foot is a good investment. There are many out there and I have numerous older machines that I have gotten a universal walking foot for as have many of my friends. They are in the $25-$30 range. For me they have worked just as well as the walking foot that came with my new machine that was specifically made for that machine.
