With right sides folded together sew the fabric for the inside pocket. Turn the pocket and then iron and top stitch the pocket. After the pocket is finished, it is top stitched to the inside lining - 1 inch up from the bottom.
Take one 11x12 piece of outside fabric and fold in half ( so the piece measures 6" x 11") - wrong sides together. Add a small piece of batting cut 6 x11" and top stitch along the fold to hold the batting in place.
