Scarf valances add a light and airy touch of elegance to any room. This window treatment is typically made of sheer, lightweight fabrics such as cotton voile, organdy, gauze, chiffon, silk or tulle. Rosettes made from the valance fabric are placed at the top corners of the valance on rectangular windows. When a scarf valance decorates a rectangular window with a semi-circular window above, the rosettes are placed in the middle of the top of the semi-circular window, and where the rectangular and semi-circular windows meet.

...
Each rosette that you add to a scarf valance will require approximately 1 yard of additional fabric.

Step 1

Measure the amount of fabric needed to make the scarf valance and rosettes. Select lightweight fabric; medium to heavyweight fabrics are not suitable for making rosettes.

Step 2

Calculate the amount of fabric that is needed for a rectangular window by adding: two times the distance from the floor to the curtain rod, plus the width of the curtain rod, plus two additional yards for two rosettes.

Step 3

Determine the amount of fabric needed for a rectangular window that has a semi-circular window above by adding two times the distance from the floor to the curtain rod, plus four times the height of the semi-circular window, plus three additional yards for three rosettes.

Step 4

Make a rosette by tying a loose knot in the fabric around your wrist, with the knot on top of your wrist. Tie a second loose knot underneath your wrist. If you are right handed, tie the knots around your left wrist, and vice versa.

Step 5

Slip your hand out of the knot. Tighten the knots and, and add volume to the rosettes by pulling fabric out of the knots, until you achieve the look that you desire.

Step 6

Determine where the rosettes are placed on a rectangular window, as follows. Mark the center of the scarf valance with a straight pin. Mark the center of the curtain rod with a light pencil mark. Drape the scarf valance over the curtain rods with the center of the scarf valance at the center of the curtain rod. Insert straight pins in the valance fabric at the right and left ends of the curtain rod. The rosettes should extend in no further than the pins you have placed at the ends of the curtain rod. Make two rosettes as described in Steps 4 and 5.

Step 7

Identify where the rosettes are placed on a rectangular window with a semi-circular window above it, as follows. Mark the center of the scarf valance with a straight pin and make a rosette in this location, as described in Steps 4 and 5. Mark the middle-top of the semi-circular window and attach a cup hook to the wall 1 inch above the edge of the middle-top of the window. Hang the center rosette on the cup hook. Attach cup hooks 1 inch from the wall edge where the semi-circular window meets the rectangular window.

Step 8

Drape the scarf valance from the top hook to each side hook. Mark the location of each side hook with a straight pin. Tie a rosette on each side. Ensure that the top edge of rosette does not extend farther than straight pin on each side. Hang the side rosettes on the side cup hooks.

Step 9

Hem the scarf valance. Put your scarf valance up on the curtain rod temporarily. Mark the location where you want to hem the valance on each side. Fold the hem 1/4 inch, press and repeat. Sew the hem using a straight stitch on a sewing machine or hem by hand.
