I was taught to never backstitch in my first quilting class. When I read quilting books, they tell you to not backstitch. I did some backstitch for the first time on my blocks this past week when I was putting together a King size quilt. I think the heaviness of the quilt was actually pulling some of my stitches loose. First time that has ever happened since I started quilting. I can't imagine backstitching when doing all of the strip piecing I do. Would take forever. You do what you want to do, there is no quilt police coming to your house !
