Lucy can be sewn by hand or by machine as you prefer. When sewing by hand, you can use a running stitch to sew the pocket pieces together and bind with a whipstitch.
There are two methods for binding the top edge. One leaves the side edges of the top binding open so the ties can be threaded through. The second uses the tape for the ties to bind the top edge. Read through both methods carefully and decide which one you wish to use.
To make sure the binding is long enough, instead of cutting the binding down you can fold under one edge and stitch the binding to the top edge but before getting to other end fold under and trim the other edge of the binding then continue the stitching.
