Cornice Lath Layout

The get-go step to any window treatment is to measure your window frame.

If you want it to exist an inside mounted treatment measure the inside expanse where the treatment volition be installed.

On the other hand, if you will be installing it exterior the window yous volition want to install information technology outside whatsoever window trim (unless y'all are making them for a dwelling house with plaster walls.) My rule of thumb is three inches outside the trim on both sides.

However, if your curtain cornice, valance, or shade is going to be installed on a door window then you may not have space for my usual 3″ install rule. Thus, your cornice volition be the window treatment will be installed the width of the window + trims + 6″ (3″ for each side.)

Figuring out the Cornice Board layout

I had a very limited amount of fabric, therefore I could not center the echo. All the same, it is platonic to center the repeat. If y'all practise not have enough cloth to cover your cornice box then you volition need to sew together fabric to your face cloth.

Using two yardsticks to layout my design helps to give me a visual before cutting. The out dominion of thumb – mensurate twice, cut once applies here.

The side legs will need to covered both outside over around and into the backside. Therefore measure your box face up and over the legs all the way to the backside.

Building a Textile Cornice Box

Your cornice box can be constructed from a multifariousness of materials such every bit foam board, cream insulation, FirmaFlex, or wood.

I chose to use plywood forest to build this cornice with plywood since information technology will last and I can easily staple into the woods.

Since this window treatment is an exterior mounted treatment it needs side pieces (legs) cut of a slice of wood attached to the front piece.

Cut Out The Confront Textile

Using a material (water-soluble) maker mark your cut line on your fabric to include and 3 inches of actress material in the length and 2 inches wider than the overall (include the within dorsum of legs) width. Excess fabric will be trimmed as needed. Mark the heart of your water both top and lesser.

Marker the center of the cornice box on both the top and lesser.

Attaching Fabric to Cornice Box

Position the face fabric on the outside of the box alining the eye marks. Starting time stapling the fabric in the center on the top of the lath. Then gently pull the fabric down from that staple and wrap the fabric to back at the bottom and staple about an inch from the lesser on the backside. Repeating the procedure until yous reach the corners.

I terminate at the corners and work on stapling the fabric to inside legs along the width first. Then I continue stapling the fabric top to bottom.

Cornice Cording

Then to decide how much cording to make I measure the board face including the outside legs and I double that number and add together 6 inches. I cutting bias strips of textile and cover the cord.

Staple the center of the cord on the center tiptop of the cornice keeping the cord straight as you staple along both sides. When you lot go to the corners you lot will demand to cut a pie shape in the seam allowance to make a corking corner. Do not cut the cord fabric only plow it back and cut off the string even with the backside the cornice.

Bring the tag to the reverse side

The lower edge's cord will need to have a  4″ tag sewn to information technology. A tag is a slice material cut at the length of the face up fabric by four″ then sew information technology to the cording. Center the cord with the tag'southward seam allowance along the bottom. Then starting in the center of the lesser edge staple the cording with tag forth the edge while keeping information technology directly.

Tack Strip

Cutting iii pieces of the cardboard tack strip.  Cut one the length of the face and cut two the length of the legs.

Staple (starting in the center) the tack strip tight equally yous can get it forth the cording. Mitering the corners then ending at the back of the legs.

After the tack strip is stapled into identify plow the tag to the inside of the cornice and staple one since from the bottom border. Notice in the photo below how the lining and gimp volition neatly end your window cornice inside dorsum.

At present is the time I terminate the top of the cornice I use the same method as I used with the tag, simply this time I am adding lining (cut lining to the measurements of the top board up and over plus ii inches extra.) In the photo beneath you tin see I used lining for the dust comprehend (the top the cornice.)

Lining The Cornice

After stapling the pinnacle lining on I turn under the sides and flip information technology over the back and staple (use a long nose stapler) as shut as possible to the height board.

Lining for the remaining backside is also done with the tack strip and the flipped down and stapled in a neat line at the lesser. To comprehend all the staples I attach gimp with hot glue.
