What is a Window Cornice?
A window cornice is a three-sided box that frames the top of a window. A cornice typically covers—and extends out over—curtain rods, the top section of blinds, and window casings. It can be as tall as you care to make it, uncomplicated or fancy.
A window cornice is typically stable, like these created from wood in this tutorial, though a window valance is customarily created from material and more like a short curtain at the top of the window. A wood window valance “box” could possibly also be called a pelmet box, which is typically more stable than a valance but coated in material to match the material.

For my wood window cornices, I made use of crown molding that matched what was by now in the space —- very conventional builder-quality things that you can obtain at any huge box keep. I also made use of some ogee trim (also known as base cap).
How to Develop a Do it yourself Wood Window Cornice
Be sure to preserve in head that all of these wood proportions and trim items are particular to my cornices—-you could want to do anything distinct.

Action one: Approach & Evaluate
Approach the glimpse of your cornice. Consider:
- What trim, if any, do you want to use?
- Will you stain it or paint it?
- How tall and broad do you want it to be?
- How substantially space do you have above and on the sides of the window to work with?
Evaluate your window from the exterior edge of the window casing on 1 aspect to the exterior edge of the window casing on the opposite aspect. Do not measure just the window by by itself. Incorporate the casings!
Your cornice will cling down around the window and the casings. I selected to incorporate 4″ (that’s 2″ for each and every aspect of the window) to my window measurements. Why? To enable for the width of the edge of the cornice and for a small space concerning the window casing and the cornice.

Also measure out from the wall to determine how deep your cornice requires to be. Will the cornice cling around a curtain rod or blinds? The cornice box requires to be deep sufficient to extend out around any obstacles—-the window casing, blinds, or curtains.
Incorporate at least a one/2″ or so to your depth measurement so you won’t have to stress about your cornice scraping up from your window treatments just after it is installed.
Centered on the clearance you have concerning the ceiling and your window, as well as your private desire, determine how tall you want your cornice to be.
Purchase your supplies and make a sketch of your proportions.
Action 2: Lower the Wood Cornice Parts & Crown Molding
I slash all the items for my cornice to start with.
I slash my 1″ x 8″ typical board to size and slash the two of the short sides at a beveled 45-diploma angle utilizing a miter observed. This piece is the front of your cornice box.
For the top and aspect items of my cornice box, I needed a shallower width of board, so I ripped my 1″ x 6″ typical board down to 1″ x 5″ (a non-conventional size not offered at my area lumber yard) utilizing a desk observed. I then slash the top and aspect items of my cornice box from the 1″ x 5″ board.
For the aspect items, I made use of my miter observed to slash 45-diploma angles on 1 of the lengthy edges.
I slash my crown molding and ogee trim, the two the front and aspect items, mitered to meet flush at the corners of the cornice box.
See this submit for ideas and means to help you discover how to slash crown molding and other trim — and always keep in mind to observe, observe, observe on some reasonably priced molding or scraps until eventually you are self-assured with your cuts.
For the ogee trim, established your table to 45-degrees. Depart your blade on center at -degrees.
For the crown molding, you will have to have to established the angles on your blade and desk in accordance to the spring angle of the crown molding you are utilizing. I made use of just about the most simple and commonly offered crown molding there is (spring angle: fifty three/37). I established my miter (angle on desk) to 31.5-degrees and my bevel (tilt of blade) to 34-degrees.
The greatest piece of crown molding, running along the top of the cornice box, has 2 exterior corners.
The still left-hand mitered exterior corner is slash by positioning the crown to the ideal of the blade. The top edge of the crown rests up from the fence. The miter angle on the desk of your miter observed is established to the ideal of center.
You will also slash the ideal-hand aspect piece of crown this way. The edge of the aspect piece of crown that fulfills the front piece of crown will be slash at an angle. The other aspect will be flush from the wall, so it is a straight-edge slash.
The ideal-hand mitered exterior corner is slash by positioning the crown to the ideal of the blade. The bottom edge of the crown rests up from the fence. The miter angle on the desk of your miter observed is established to the still left of center.
You will also slash the still left-hand aspect piece of crown this way. The edge of the aspect piece of crown that fulfills the front piece of crown will be slash at an angle. The other aspect will be flush from the wall, so it is a straight-edge slash.
When chopping crown, I always incorporate a half-inch or a small more to the full size I measured prior to chopping. I’ll do a test in good shape just after generating my to start with slash and then trim a small more off if I have to have to, but with crown, when you slash it too short, you are out of luck! So I’m always incredibly, incredibly careful and take my time to be guaranteed to get it ideal. Preserve in head, too, that crown has to extend a little bit past the size of your cornice box. If the slash edge of the crown traces up just with the edge of the cornice box, there won’t be sufficient of an edge still left on the crown to meet up with the edge of the aspect piece of crown, which you will want it to do in buy to get a neat corner.
Action three: Assemble the Wood Cornice
I drilled holes utilizing my Kreg Jig along the top, inside edges of my front box piece and my 2 aspect box items. (If you never have a Kreg Jig, you can join your box collectively by to start with gluing with wood glue and then utilizing finishing nails or a nail gun.)
I made use of wood glue to join the mitered edges of my aspect box items and my front box piece and clamped it all to dry. Then, I made use of my eighteen-gauge nail gun to boost the bond by nailing the items collectively (you could also use a hammer and finishing nails, if you never have a nail gun).
Upcoming, I made use of my Kreg Jig screws to screw collectively the top piece of my box to the front and aspect box items. Now, you have got your self a box. Time to jazz it up!
Action four: Connect Cornice Trim
I connected the ogee trim flush to the bottom edge of my cornice box with my eighteen-gauge nail gun (you can also use finishing nails and a hammer). You can glue to start with, too, if you’d like to.
Right before attaching any trim, nevertheless, test the in good shape of your corner items to make guaranteed they in good shape collectively effectively.
Make measured marks all along the size of your box where you want your crown molding to be. Then, use a amount or other straight edge to link the marks so you have a line along which to line up the bottom edge of your crown molding—you want it to be amount. Nail along the bottom edge of your crown to connect it to your cornice box. It can be anywhere on the box frame you pick out for it to be—-flush with the top edge of the box or someplace farther down the box. I selected to have a 5-one/2″ gap concerning the top of my ogee trim and the bottom of my crown molding.
You can always incorporate a shelf to the top of the cornice box, which would give the crown anything to connect to (like it would if it have been staying equipped along a wall and ceiling), but considering the fact that on this cornice, I selected not to incorporate a shelf, I had to glue the corner crown items to the center crown piece to connect them.
Use painter’s tape to protected the link until eventually the glue dries. Connect the bottom of the aspect items of crown with nails along the bottom edge, just as you did with the front piece of crown.
I would suggest from trying to nail the top piece of the aspect crown to the top piece of the front crown, as you’ll risk splitting the crown.
Action 5: Complete and Paint Your Window Cornice
Now, use wood filler on your nail holes and caulk all the seams.

Immediately after the wood filler and caulk have dried, do a light sanding to be certain a sleek finished surface area. Wipe away all dust and particles.
I made use of 1 coat of primer and two coats of paint, letting every little thing dry extensively concerning coats.
Don’t forget to paint the underside of your cornice box, too, as it will be obvious if an individual is standing shut to, or underneath, the window.
If the top of your cornice box will be obvious, be guaranteed to paint the top, too, but most of the time, a cornice box will be so shut to the ceiling that no 1 will be equipped to see the top of it.
How to Cling a Wood Window Cornice
Lower a 1″ x 2″ strip of wood just shorter than the full size of your done cornice box.
Mount it to the wall above the window where you will be hanging the cornice, utilizing a amount and 2″ wood screws. Be guaranteed to connect to studs and not just dry wall.
Preserve in head how far down around your window you want your cornice to hang—-that will determine where on the wall you install the 1″ x 2″ strip of wood (your cornice box will ‘hang’ on this strip of wood).
You will connect your window cornice box by ‘hanging’ it on, and screwing it in to, your 1″ x 2″ strip, which you have mounted to the wall above your window. It won’t be protected sufficient to just ‘hang’ the cornice box on the 1″ x 2″ strip. You have to have to screw down through the top of the cornice box, in to the 1″ x 2″ strip at typical intervals along the size of the cornice box.
To make the career much easier, I screwed my 2″ wood screws partially in to the top of my cornice box prior to hanging it, so that I’d have less screwing to do just after placing the cornice box in place around the window. Be mindful in the placement of your screws. You never want them so shut to the edge that the wood splits, hence compromising the attachment. Neither do you never want them so far away from the edge that they won’t screw down in to the top of your wall-mounted 1″ x 2″ strip.
You can also use the identical idea to develop a decorative and/or functional shelf.
As an alternative of generating a box as you did for the cornice, use just a flat board and incorporate a shelf on top. Connect trim just as you would for the window cornice. I made use of an Ook Hangman French Cleat Image Hanging Package to cling the shelf down below in my kitchen—-operates like a desire! And, indeed, you can cling it someplace other than around a window!
