Can I replace just the “thingy” I am missing from the q.foot?
I would appreciate any help you all can give with these probably elementary questions. The “quilting foot” is probably just a guide that is supposed to help you stitch rows of quilting stitches an even distance from each other. If you want to sew grids on your quilt, it might be useful. But a walking foot is entirely different. It is a big, hunky foot that entirely replaces your regular presser foot. It has feed dogs that help feed the top layer of your fabric through, the same way the feed dogs on your machine feed the bottom layer through. If you want to do quilting in straight lines, it can be very useful, helping you avoid accidental “pleats” of fabric on the top or bottom. But first try quilting with your regular presser foot–just use a longer stitch than normal, and practice on a scrap to see if you need to adjust the tension in your top or bottom thread. If you want to do curved lines of quilting, you need another foot called a “free motion embroidery foot” or a “darning” foot.
