I prefer to interline the drapery with a black felt fabric between the face fabric and lining. You can get it in about 70"wide. If your draperies are short you can run the interlining horizontally so you need not seam it. Just tuck it between the face and lining fabrics at the top and side. Don't turn it with the hems and headings as it will get too bulky. Cut the bottom edge just a bit longer than the top of the bottom hem. Let it hang freely between the fabrics. It not only darkens the room , it gives the face fabric a great rich look. I use felt in all the draperies I make. Hope this helps.
