Do not use the regular sewing foot. You can use an embroidery foot, or quilting/darning foot with circular hole. I have even done it without any foot. MANY years ago I used a little spring device that fit over the bar by the needle that cost $1.(!) I didn't know at that time that my OLD Singer had a way to drop the feed dogs, but I covered them with tape. I darned LOTS of my kids socks that way, before I ever thought about quilting, and it would have worked the same way. I have stippled several quilts now. Just takes PRACTICE!! Don't give up! I still like my 55 year old Singer in a cabinet better than the machines that don't have a large flat working area.
