I have a singer 403 a that uses cams and I am wondering if this is a blind hem stitch or a blanket stitch. I am needing a blanket stitch for applique and if you look at the finer stitching it still leaves a < shape in the zag part. So thinking that I have the wrong cam. I also posted the stitch in wide length so that may help in your determination.
Thanks for your help!
