Measure the width of your window between your curtain rod’s brackets. Add 1 inch to this measurement to find your fabric’s length. Decide how far down you want the lowest portion of the scallops to extend from the rod (typically 12 to 16 inches). Add 3 inches to this measurement to find your fabric’s width. - 2). Cut your valance fabric, lining fabric and craft paper to the size determined in Step One. Pair the two fabrics together with the right sides of the pattern facing in. Pin the edges along all four sides.
- 3). Divide the width of your window by three to find the width of each scallop. Fold the craft paper in half widthwise. Draw a half scallop, starting at the lowest point and swooping up, from the fold and running along the edge. Draw a full scallop immediately after the half scallop which extends to the corner of the paper.
- 4). Cut the craft paper on your drawn line and open the fold to reveal three scallops. Lay the craft paper over your fabric and lining from Step Two with the scalloped portion paired with one of the long sides. Adjust the scallops to be a 1/2 inch away from the raw edges of the fabric.
- 5). Trace the scallops onto your fabric with a water soluble fabric marker. Remove the paper. Sew along the traced scallop lines and up the sides of the valance with a 1/4-inch seam. Sew a 1/4-inch seam along the top of the valance, but leave open a 10-inch section.
- 6). Turn the valance right side out through the 10-inch opening and press the seams flat with a hot iron. Sew the opening closed. Fold the top edge over to the lining side by 2 inches and sew to create a pocket for the curtain rod.
