Things You'll Need:
- Fabric
- Measuring tape
- Fabric pen
- Scissors
-
Step 1
Determine the length of fabric you need. Measure the length of the valance board, being sure to include the width of the board itself. This means, if your valance board is 3 ½ inches wide, you have to include 7 inches to your measurement (3 ½ inches on each side).
-
Step 2
Add 10 inches for the center pleat. After you finish measuring the length of the curtain valance, you have to add 10 to allow for a large center pleat.
-
Step 3
Include the seam allowance. Add ¼ of an inch to the length of the fabric in order to allow for seams.
-
Step 4
Mark your measurements. Use a fabric pen or any type of pen to mark where you need to cut your valance.
-
Step 5
Cut fabric for valance curtains on a flat surface. Lay your fabric out on a smooth flat surface to make sure your cuts are clean and even.
