When sewing two raw edges of fine lace together, like
the tiny lace ruffles on lingerie blouses or dresses, do not fell it in
the old-fashioned way, but place the two right sides together and bind the
edge with the finest thread, making a buttonhole stitch along the edges.
Put a stitch in each mesh, and you will have a neat lace seam which, when
pressed, can scarcely be observed, and it will not fray.
