Step 1
Lay the valance fabric flat on a table or other work surface, with the most attractive side up. Do the same with the lining fabric, which you have cut to the same size as the valance fabric.
-
Step 2
Place the valance fabric on top with the attractive side down. Ensure that the two blocks of fabric match on all edges.
-
Step 3
Pin the two fabrics together along one long edge. If the valance fabric pattern defines an "up" direction, pin along the bottom edge.
-
Step 4
Sew the long pinned edges together. Leave a 1/2-inch seam allowance by sewing the edges together 1/2 inch from the raw edges. Use a straight stitch and relatively small stitches.
-
Step 5
Turn the fabrics right side out. Roll down the seam allowing 1/2 inch of valance fabric to be visible on the back. Iron the seam flat. Let the fabric cool before proceeding.
-
Step 6
Switch the fabrics to the wrong side out again, letting the valance fabric crease where it was ironed as the two fabrics lay together on the short edges.
-
Step 7
Tack the valance fabric and lining fabric together on each short end with pins. Sew each with a 1/2-inch seam allowance. Reverse the fabrics right side out, letting the bottom edge crease where it was ironed in Step 4.
-
Step 8
Iron along all three seams after turning the short ends inside out exactly at the seam. Cut the extra 1/2 inch of lining fabric from the top edge and baste the edges together. Adhere the curtain to the valance board.
