Walking foot alternatives?
As I understand it, a walking foot's purpose is to preserve the alignment of the fabric sandwich as it passes under the needle, i.e., not push the top layer of fabric forward as a standard foot tends to do. Try as I might, I haven't been able to find a walking foot attachment for my Singer 31-15 (tailor's machine). I'd like to take advantage of its larger throat space to stitch the layers of a big quilt I'm making. Would a roller foot be better? Suggestions?
