Materials:

- Fabric
- Lining
- Measuring Tape

Steps:

1. To make the lined, flat panels, cut the lining the same length as the fabric and four inches narrower. Fold the bottom edge of the fabric over two inches, and then four inches to make a hem. Stitch the hem in place, leaving six inches unsewn at both ends. On the lining, turn up a double two-inch hem along the bottom edge and stitch the entire length of the hem in place.

2. Lay the fabric and the lining down with right sides facing and the lining hem 1-1/2 inch above the fabric hem and centered so there are two inches of fabric showing on each side (the lining will extend past the top of the drapery panel by 1-1/2 inch).

3. Pin the sides together and sew the side seams in place, stopping about two inches short of the lining hem. Turn the panel right side out and center the lining on the drapery panel. Press the side edges flat.

4. To make a mitered fold at the corners, mark the point where the fold of the side edge and the fold of the hem meet with a pin and open the fabric. Fold the fabric diagonally across the corner so the pin is exactly on the edge of the fold, and the top and side of the flap are parallel to the bottom and side of the curtain. To refold the hems, crease along the fold and turn in the side hem, followed by the base hem. Slip-stitch the edges of the miter together and along the unstitched part of the hem. Pull the lining down over the drapery hem and slip-stitch down the side and along the bottom edge for about one inch.

5. To make the header, cut the excess lining, and then fold over the fabric and the lining together to the height required for the finished drapery panel. Stitch along the fold and the panel is complete.
