How to Build a Wood Window Valance

Adding decorative window treatments can set the tone for your décor, whether floor-to-ceiling drapes or simple mini-blinds. Hiding the hardware at the top is the primary function of a box valance or cornice board. Building your own window valance from wood is easy and quick and costs very little. With a trip to the hardware store, a few simple tools and an afternoon of free time you can make your own decorating ideas come to life.

Things You'll Need

• Carpenter's square
• 1-by-12-inch pine
• 2-inch L brackets and screws
• 1 5/8-inch drywall screws or drywall anchors
• Hammer and nails
• Wood glue
• Sander or sanding block and sandpaper

Instructions

Cutting the Valance

1. Use a carpenter's square to mark the three main pieces for your DIY window valance from the 1-by-12-inch pine. First mark the valance face 3 inches wider than the window's outside measurement.

2. Mark two returns at 6 inches each. These will be the "leg" sections that hold the valance away from the wall.

3. Cut all three pieces carefully with a circular saw. Keep the saw on the line to make sure you have a 90-degree angle.

Assembling a Wood Valance

1. Attach the two return pieces to the ends of the valance face to form a "U" shape. Use wood glue and finish nails.

2. Reinforce the inside corners of the returns with L brackets. Make sure to use screws that are no more than 3/4 inch long to avoid piercing the face. Predrill pilot holes and tighten screws with a screwdriver for best results. Use one L bracket per corner, placed in the middle of the joint.

3. Attach four L brackets on the inside of the returns at each of the four corners. The L should be perpendicular to the return. Use at least two screws on each bracket to avoid spinning.

Installing a Wood Valance

1. Check for framing with a hammer and finish nail just outside the window frame's top corner. If the nail hits solid wood you can hang your valance using 1 5/8-inch drywall screws. If it sinks easily and feels loose, drill and install sheetrock anchors.

2. Hold the valance in place--1 or 2 inches above the top of the window trim and centered on the window-- on the wall with a helper. Mark the holes where the L brackets meet the wall. Take the valance down carefully after marking. Predrill pilot holes for drywall screws, or install anchors at these points. Follow manufacturer's instructions for anchor installation.

3. Lift the valance into place and make sure the weight is well supported. Use a drill and screw bit to place screws in each of the pre-drilled holes or anchors. Snug them down well and gently let the weight rest on the hardware. Make sure the weight is well supported before adding window treatments such as drapes or blinds.

Tips & Warnings

• Use a sander, or sandpaper and a sanding block, to smooth any rough edges before staining or painting.
