I had never heard about not reversing with a walking foot, thank you. Early on, when learning about quilting, somebody told me that if your seam will be crossed by another seam, backstitching in not necessary. Makes sense to me and I've been doing it that way ever since.
When we sewed on my mother's old singer, we always secured the seams by stitching off the end and then lifting the foot and sliding it back and stitching to the end again. When we got a machine that reversed, we felt like we had moved uptown. Now we all have computerized machines and are in seventh heaven. What an explosion of technology in my lifetime!!!
