Lining should be cut to allow for a 2″ hem at the bottom and a ½″ seam across the top and sides.
Illustration is for a drapery 2½ yards long, finished with 4″ top hem, 1″ side hems and 3″ bottom hem. Drapery length would measure 98½″ and lining length, 88½″. The average hem widths, 3″ and 4″, were used in figuring measurements. The width of hems vary. There is no fixed rule. They may be 3″—4″—5″ or even 7″ at the top and 2″—2½″—3″ or 4″ at the bottom. In many cases the bottom hem is doubled, particularly in sheer or lightweight fabrics. Also the center side hem may be as much as 2″ wide and the outer hem 1″. In this case, the lining is cut 6″ narrower than the drapery. Before taking measurements for draperies, review section on [Window Measurements].
To join lining, turn top edge of lining to underside ½″ and press. Pin lining and drapery together, starting 7½″ from the top. Stitch from top of lining down to 4½″ of lower edge of lining, taking a ½″ seam. Back-stitch at the beginning and end of seam. Press seam as stitched; then clip seam every 3″ or 4″. Press the seam open. Pin, from hem to hem, a 4″ wide strip of stiffening to underside across the top. Stitch and press.
