Instructions for Tailored Valances
- 1). Measure the distance between the outer edges of the window molding. Measure the width of the window opening in the wall if you don't have molding. Add 2 inches for the finished valance width.
- 2). Fold the valance fabric to different lengths - typically from 12 to 20 inches -- and hold it up to the window to choose a finished hanging length. Hold the folded fabric from various points above the window to choose a mounting height. Mark your chosen mounting height on the wall with a pencil.
- 3). Divide the finished width by two, and add 15 inches. Add 2 1/2 inches to the finished length. Cut one width of fabric -- which means cutting crosswise -- to those measurements.
- 4). Divide the finished width by two, and add 11 1/2 inches. Add 2 1/2 inches to the finished length. Cut one width of fabric to those measurements.
- 5). Lay the cut fabric from Step 1 right side up. Place the cut fabric from Step 2 right side down on top of the first. Align the rightmost edges and pin them together. Machine sew the edges together with a 1/4-inch seam allowance. Remove the pins.
- 6). Lay the fabric right side down on an ironing board. Pin 3/4-inch fusing tape to the leftmost edge. Fold the leftmost edge of the fabric over 1 inch and pin. Fuse the fold together with an iron, according to the fusing tape instructions. Remove the pins. Repeat with the rightmost edge of the fabric and then with the bottom.
- 7). Divide the finished valance width by two for the half-width measurement. Start at the left, with the fabric right side up, and place pins at the following intervals: 3 inches, 6 inches, half width, 6 inches, half width and 6 inches. Pin along the bottom hem, with the pinheads at the edge. You'll end up with three pairs of pins spaced 6 inches apart.
- 8). Lay the valance fabric right side up, with the bottom edge facing you. Starting from the left, find the first pair of 6-inch spaced pins. Hold a pinhead in each hand and lift the fabric. Bring the pins together to form an inverted box pleat. Pin the pleat into place at the top of the valance fabric. Repeat with the remaining pairs of 6-inch spaced pins.
- 9). Cut 3/4-inch plywood 3 inches by the finished valance width to make a mounting board. Align the centers of the two outermost pleats with the front corners of the board, with the wrong side of the fabric facing the board. Fold the top 1 1/2 inches of the valance over the top of the mounting board. Staple the fabric to the top of the board along the front and both 3-inch sides. Remove the pins.
Screw L-brackets into both ends of the underside of the mounting board. Space additional L-brackets every 16 to 24 inches, depending on the spacing of your wall studs. Align the corners of the brackets with the mounting board's back, with the L-end hanging down. Screw the hanging ends of the L-brackets into the wall, at the mounting height you marked in Step 2.
