Cornice Creations™ cornices are assembled without special sewings skills. Using our slotted channel design, fabric panels are simply inserted to create the look you want! Best of all, the panels can be easily removed for cleaning or replacement (if, you want to create a totally different look)!

The following instructions illustrate the basic techniques necessary to fabricate a Cornice Creation.


Required Supplies: Tape measure (preferably a flexible tailoring tape), sharp carving knife, scissors, tape, spray adhesive, valance rod kit (found at craft, hardware, or home stores), and sewing machine (optional).


1. Setting the rod width:

A. The first step is to set the rod to the desired width. The rod should extend past each side of window by at least 2" (See Figure 2). (DO NOT MOUNT NOW)

B. After adjusting the rod, tape the joint(s) of the rod to keep it from changing size.

Note: The slotted channels contain a small foam core that should be removed before proceeding with the cornice assembly. If necessary, these foam core pieces may be re-installed after the fabric has been tucked in to help lock the material into place.

2. Forming the returns (sides):

The cornice returns or "sides" enable you to mount the cornice over many types of window treatments such as curtains, roller shades, mini blinds, or pleated shades.

To form the return sections:

A. As you can see, the returns have a large edge and a small edge. You have the choice of making the return 4-1/2”, 7-1/2”, or you may cut the return down with a sharp carving knife to a desired length. We recommend not going lower than a 3” return.

B. Spray a uniform amount of adhesive into the "V" channel on the backside of each return (See figure 3). Let glue become tacky then fold returns over making sure those sections are aligned. Let the glue dry before proceeding to next step.

C. Press the rod into the selected channel on the backside of each return (See figure 4).

Note: For proper mounting, the rod should always be located at the topmost channel on the back of the cornice.

3. Measuring and cutting the center cornice section:

A. Measure between the returns to determine the required width of the center section(s). Multiple center sections (Extender Kits) can be glued together to create a wider cornice.

B. Cut the center section(s) to the required size by first measuring and marking a straight line across the section then carefully cutting along the line using the sharp carving knife (See figure 5).

4. Gluing the cornice sections:

A. Remove the rod from the return sections. Spray a uniform amount of adhesive onto the ends of all cornice sections that are to be joined (See Figure 6). After the adhesive has become tacky, carefully align the front edges of the cornice sections and firmly press together. Let the bonded cornice set for several minutes before re-inserting the rod and proceeding to the next step.

5. Measuring for the fabric panels:

All cornice kits will require between 1-1/2 and 2-1/2 yards of fabric depending on the look you wish to create. Extender sections will require between 1-1/4 and 2-1/4 yards of fabric. Select the channels you wish to use to create your design then follow the measuring steps indicated below.

Measuring for panel length: Use tape measure, insert it fully into the rear channel, wrap it around the face of the cornice and tuck it into the desired front channel. Add 1" extra to panel length for tuck in (See Figure 7). This final measurement will be the panel's finished length. Repeat this procedure for each panel.

Measuring for panel width: Measure across the width of each cornice section, including the returns. Add at least 2" to the width measurement to allow for fabric to be folded over at return ends. This measurement will be the panel's finished width.

Note: To create a gathered panel double the width (horizontal) measurement for medium weight fabrics and triple the width measurement for thin fabrics. (Thick fabrics will not gather well.) Cut fabric into panels using the measurements from the previous steps.

Sewing the panels (optional step): Pre-gathering the panels using a gathering attachment on your sewing machine (sometimes called a ruffler) will speed up your assembly time and give you a more consistent look. A beautiful look can be accomplished by pinching the material into gathers as it is being tucked in.

6. Applying fabric panels:

Gathered panel - Lay panel uniformly across cornice. Starting from the returns tuck the fabric into the channels at each end of the return. Working toward the center of the cornice pinch the fabric into gathers making sure that gathers are consistent (See Figure 8).

Pre-Gathered panels - Starting from the returns tuck the fabric into the channels at each end of the return. Working toward the center of the cornice tuck the pre-gathered panel into place making sure that gathering is consistent along width.

Flat panel - Lay panel across cornice. Starting from the center and working outward, tuck the panel into the channels, making sure material is even and taut. Leaving one inch of fabric at each return end cut off any remaining fabric. Fold the material under itself and tuck into the channels (See Figure 9). It may be necessary to form a small pleat at the return corner so material can make a graceful wrap around the face of the cornice. If needed, a small drop of glue may be used to hold material into place at the returns.

7. Finishing the cornice:

For a beautiful finishing touch decorative trim such as welting, braiding, or fabric overlays can be added to achieve your desired look (See Figure 10). Some styles may also be accented with wallpaper, vertical vane, or reflective Mylar inserts.

Note: The coloring of the cornice will deepen with time. This is a normal condition inherent with many foam products. This will in no way affect its structural performance.

8. Installation:

Mount end brackets of curtain rod at desired location on wall. If using extender kit(s) install the support bracket(s) at same level as end brackets (See Figure 11). Hook each end of curtain rod into end brackets to install. Hook wire of center support around bottom side of rod to support center section of cornice. Dress the material making sure it is even and straight.
