I tried several different ways to avoid using pins and like the Elmers glue the best.
You dont need to remove the quilt when you sew to the 1/4 inch in the corners if you just back stitch off then pull the quilt out enough to fold the binding over then just continue sewing the binding on. That is how Eleanor Burns does it.
You can also use a zig zag stitch to sew the back side down.
