This is a lesson at Seams To Be Sew that originally shows how to create shapes in a Machine Embroidery Hoop that uses the technique where you place right sides together, stitch around the shape and turn it inside out. Doing this via a in the hoop method allows all the pieces to be sewn at the same time.
