I have had my Brother 8500 for years and years. I just discovered recently that there is a stich that is a straight stitch ''R" with a P beside it. It is called a quilt piecing stitching. It is just a scant 1/4" perfect. I had purchased all kinds of 1/4" feet an accesories and here I had it all these years. I don't wander around as much with it.
