This is chiefly used as a trimming for blouses ana other garments of thin material, where it is desirable that one or more bands of material be fastened together by lacy open work.
Take a narrow strip of cross-cut lawn or similar material about 1 inch wide and fold both edges inwards, forming a narrow band about 1/3 to 1/2 inch wide. Tack this in a straight or curved line, as the required shaping demands, to a firm piece of cardboard, taking care not to pull out the material too tight. Then lay the hem of the material to be trimmed (or a corresponding band) parallel to the first and tack to the cardboard.
If many bands are required to be shaped, for instance, into a neckband, it is advisable to draw the shape out on the cardboard and to tack the bands into place along both edges (Diag. 145B).
