3. Calculate the cut fabric width as the width of the valance plus twice the width of the mounting board (the return) plus 2 inches. For a window 48 inches wide, mounted on a 1-by-2 inch board, the fabric cut width is 52 1/4.lace the straight edge at this measurement. Fold the valance fabric up and over the straight edge. The right side of the fabric is now on the surface, and you now have a 2-fold valance. Align the top edges and re-position the pins to include all 4 layers. Sew across the top of the valance 3/4 inch from the raw edges.
