How to Create a Do-it-yourself Wood Window Cornice
You should continue to keep in mind that all of these wood dimensions and trim items are certain to my cornices—-you may well want to do one thing distinct.

Phase 1: Strategy & Evaluate
Strategy the appear of your cornice. Take into account:
- What trim, if any, do you want to use?
- Will you stain it or paint it?
- How tall and wide do you want it to be?
- How substantially room do you have higher than and on the sides of the window to work with?
Evaluate your window from the exterior edge of the window casing on 1 facet to the exterior edge of the window casing on the opposite facet. Do not measure just the window by by itself. Include things like the casings!
Your cornice will cling down more than the window and the casings. I chose to incorporate 4″ (that’s 2″ for each and every facet of the window) to my window measurements. Why? To permit for the width of the edge of the cornice and for a minor room amongst the window casing and the cornice.

Also measure out from the wall to ascertain how deep your cornice demands to be. Will the cornice cling more than a curtain rod or blinds? The cornice box demands to be deep adequate to lengthen out more than any obstacles—-the window casing, blinds, or curtains.
Include at the very least a 1/2″ or so to your depth measurement so you won’t have to fear about your cornice scraping up versus your window solutions soon after it’s installed.
Based mostly on the clearance you have amongst the ceiling and your window, as properly as your individual desire, ascertain how tall you want your cornice to be.
Order your materials and make a sketch of your dimensions.
Phase 2: Slice the Wood Cornice Parts & Crown Molding
I reduce all the items for my cornice initial.
I reduce my 1″ x 8″ widespread board to duration and reduce both of the quick sides at a beveled forty five-degree angle making use of a miter saw. This piece is the front of your cornice box.
For the top rated and facet items of my cornice box, I required a shallower width of board, so I ripped my 1″ x 6″ widespread board down to 1″ x 5″ (a non-normal dimensions not accessible at my area lumber garden) making use of a desk saw. I then reduce the top rated and facet items of my cornice box from the 1″ x 5″ board.
For the facet items, I utilized my miter saw to reduce forty five-degree angles on 1 of the prolonged edges.
I reduce my crown molding and ogee trim, both the front and facet items, mitered to meet up with flush at the corners of the cornice box.
See this submit for suggestions and sources to help you find out how to reduce crown molding and other trim — and generally remember to practice, practice, practice on some economical molding or scraps till you are assured with your cuts.
For the ogee trim, established your table to forty five-levels. Depart your blade on centre at -levels.
For the crown molding, you’ll require to established the angles on your blade and desk according to the spring angle of the crown molding you are making use of. I utilized just about the most primary and commonly accessible crown molding there is (spring angle: 53/37). I established my miter (angle on desk) to 31.five-levels and my bevel (tilt of blade) to 34-levels.
The most significant piece of crown molding, working alongside the top rated of the cornice box, has 2 exterior corners.
The still left-hand mitered exterior corner is reduce by positioning the crown to the ideal of the blade. The top rated edge of the crown rests up versus the fence. The miter angle on the desk of your miter saw is established to the ideal of centre.
You will also reduce the ideal-hand facet piece of crown this way. The edge of the facet piece of crown that satisfies the front piece of crown will be reduce at an angle. The other facet will be flush versus the wall, so it’s a straight-edge reduce.
The ideal-hand mitered exterior corner is reduce by positioning the crown to the ideal of the blade. The base edge of the crown rests up versus the fence. The miter angle on the desk of your miter saw is established to the still left of centre.
You will also reduce the still left-hand facet piece of crown this way. The edge of the facet piece of crown that satisfies the front piece of crown will be reduce at an angle. The other facet will be flush versus the wall, so it’s a straight-edge reduce.
When chopping crown, I generally incorporate a half-inch or a minor extra to the total duration I calculated before chopping. I’ll do a examination fit soon after making my initial reduce and then trim a minor extra off if I require to, but with crown, as soon as you reduce it also quick, you are out of luck! So I’m generally very, very careful and choose my time to be sure to get it ideal. Hold in mind, also, that crown has to lengthen a bit previous the duration of your cornice box. If the reduce edge of the crown lines up specifically with the edge of the cornice box, there won’t be adequate of an edge still left on the crown to meet up with up with the edge of the facet piece of crown, which you’ll want it to do in get to get a neat corner.
Phase 3: Assemble the Wood Cornice
I drilled holes making use of my Kreg Jig alongside the top rated, inside edges of my front box piece and my 2 facet box items. (If you really do not own a Kreg Jig, you can be a part of your box together by initial gluing with wood glue and then making use of finishing nails or a nail gun.)
I utilized wood glue to be a part of the mitered edges of my facet box items and my front box piece and clamped it all to dry. Then, I utilized my eighteen-gauge nail gun to reinforce the bond by nailing the items together (you could also use a hammer and finishing nails, if you really do not have a nail gun).
Up coming, I utilized my Kreg Jig screws to screw together the top rated piece of my box to the front and facet box items. Now, you have obtained by yourself a box. Time to jazz it up!
Phase four: Attach Cornice Trim
I attached the ogee trim flush to the base edge of my cornice box with my eighteen-gauge nail gun (you can also use finishing nails and a hammer). You can glue initial, also, if you’d like to.
Right before attaching any trim, however, examination the fit of your corner items to make sure they fit together properly.
Make calculated marks all alongside the duration of your box exactly 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 alongside which to line up the base edge of your crown molding—you want it to be amount. Nail alongside the base edge of your crown to connect it to your cornice box. It can be everywhere on the box frame you opt for for it to be—-flush with the top rated edge of the box or somewhere farther down the box. I chose to have a five-1/2″ gap amongst the top rated of my ogee trim and the base of my crown molding.
You can generally incorporate a shelf to the top rated of the cornice box, which would give the crown one thing to connect to (like it would if it ended up getting fitted alongside a wall and ceiling), but given that on this cornice, I chose not to incorporate a shelf, I had to glue the corner crown items to the centre crown piece to connect them.
Use painter’s tape to secure the connection till the glue dries. Attach the base of the facet items of crown with nails alongside the base edge, just as you did with the front piece of crown.
I would advise versus trying to nail the top rated piece of the facet crown to the top rated piece of the front crown, as you’ll risk splitting the crown.
Phase five: End and Paint Your Window Cornice
Now, use wood filler on your nail holes and caulk all the seams.
Beneficial Examining: Ideas for Caulking Like a Pro
After the wood filler and caulk have dried, do a mild sanding to guarantee a clean completed floor. Wipe away all dust and debris.
I utilized 1 coat of primer and two coats of paint, letting all the things dry comprehensively amongst coats.
Don’t forget to paint the underside of your cornice box, also, as it will be visible if anyone is standing close to, or less than, the window.
If the top rated of your cornice box will be visible, be sure to paint the top rated, also, but most of the time, a cornice box will be so close to the ceiling that no 1 will be in a position to see the top rated of it.
How to Dangle a Wood Window Cornice
Slice a 1″ x 2″ strip of wood just shorter than the complete duration of your completed cornice box.
Mount it to the wall higher than the window exactly where you’ll be hanging the cornice, making use of a amount and 2″ wood screws. Be sure to connect to studs and not just dry wall.
Hold in mind how far down more than your window you want your cornice to hang—-that will ascertain exactly where on the wall you put in 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 higher than your window. It won’t be secure adequate to just ‘hang’ the cornice box on the 1″ x 2″ strip. You require to screw down by way of the top rated of the cornice box, in to the 1″ x 2″ strip at common intervals alongside the duration of the cornice box.
To make the occupation less complicated, I screwed my 2″ wood screws partly in to the top rated of my cornice box before hanging it, so that I’d have fewer screwing to do soon after putting the cornice box in position more than the window. Be mindful in the placement of your screws. You really do not want them so close to the edge that the wood splits, as a result compromising the attachment. Neither do you really do not want them so far away from the edge that they won’t screw down in to the top rated of your wall-mounted 1″ x 2″ strip.
You can also use the exact strategy to produce a decorative and/or useful shelf.
Alternatively of making a box as you did for the cornice, use just a flat board and incorporate a shelf on top rated. Attach trim just as you would for the window cornice. I utilized an Ook Hangman French Cleat Picture Hanging Kit to cling the shelf below in my kitchen—-functions like a aspiration! And, yes, you can cling it somewhere other than more than a window!
