Next layer the outside piece that was made from the folded fabric and batting. Line up the bottom edges. The length of the bag at this point is 12 inches and it is 11 inches wide.
Two pieces of ribbon 14" or so in length pinned to the middle of the top and bottom edge. Place the edge of the ribbon along the outer edge of the fabric and the ribbon pointing inward. ( I tuck the ribbon inside a bit so I don't sew over it)
