In my son’s room, the window is on the wall opposite the door. The window is the focal point of the room, the first matter you see. I dressed it up with a Do-it-yourself window cornice. The cornice adds weight and visible interest. It is also a attractive accent that adds a bold pop of shade to the room. (I preferred how it turned out so well, that I made similar cornices for my other sons’ rooms.)

A window cornice is a 3-sided box that frames the best of a window. A cornice generally covers—and extends out over—curtain rods, the best part of blinds, and window casings. It can be as tall as you treatment to make it, simple or extravagant.

A window cornice is generally stable, like these made from wood in this tutorial, although a window valance is ordinarily made from cloth and extra like a small curtain at the best of the window. A wood window valance “box” could also be known as a pelmet box, which is generally extra stable than a valance but included in cloth to match the drapery.

Regardless of whether you get in touch with it a window cornice, valance, or pelmet, the goal is to include up the window hardware and give your home windows some presence and design!

How to Create a Do-it-yourself Wood Window Cornice

You should preserve in mind that all of these wood proportions and trim parts are certain to my cornices—-you could want to do some thing distinctive. For illustration, I applied a 1″ x 8″ board for my cornice box, but if you want a taller (or shorter) cornice box, you’d want to obtain a broader, or shorter, board, and so on.

*This is a tender and inexpensive wood. It generally has knots and is in some cases not straight, so be choosy when deciding on your wood. Get the straightest doable parts with the fewest knots.

Move one: System & Measure

System the glance 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 considerably place do you have over and on the sides of the window to get the job done with?

Measure your window from the outside edge of the window casing on a single side to the outside edge of the window casing on the opposite side. Do not evaluate just the window by alone. Consist of the casings!

Your cornice will cling down more than the window and the casings. I selected to increase 4″ (that is 2″ for each side of the window) to my window measurements. Why? To allow for for the width of the edge of the cornice and for a minimal place in between the window casing and the cornice.

Also evaluate out from the wall to identify how deep your cornice requirements to be. Will the cornice cling more than a curtain rod or blinds? The cornice box requirements to be deep ample to lengthen out more than any obstacles—-the window casing, blinds, or curtains.

Incorporate at minimum a one/2″ or so to your depth measurement so you will not have to worry about your cornice scraping up towards your window solutions after it’s mounted.

Based mostly on the clearance you have in between the ceiling and your window, as well as your individual preference, identify how tall you want your cornice to be.

Move 2: Slice the Wood Cornice Items & Crown Molding

DIY Wood Window Cornice | detailed step-by-step photo tutorial to build and hang a window cornice, on Remodelaholic.com

I lower all the parts for my cornice first.

I lower my 1″ x 8″ widespread board to length and lower both equally of the small sides at a beveled forty five-degree angle working with a miter saw. This piece is the entrance of your cornice box.

For the best and side parts 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-standard dimensions not out there at my nearby lumber property) working with a table saw. I then lower the best and side parts of my cornice box from the 1″ x 5″ board.

For the side parts, I applied my miter saw to lower forty five-degree angles on a single of the extensive edges.

I lower my crown molding and ogee trim, both equally the entrance and side parts, mitered to meet flush at the corners of the cornice box.

See this publish for ideas and assets to enable you study how to lower crown molding and other trim — and constantly recall to exercise, exercise, exercise on some inexpensive molding or scraps until finally you’re self-assured with your cuts. 

For the ogee trim, established your table to forty five-levels. Leave your blade on heart at -levels.

For the crown molding, you will have to have to established the angles on your blade and table according to the spring angle of the crown molding you’re working with. I applied just about the most fundamental and greatly out there crown molding there is (spring angle: 53/37). I established my miter (angle on table) to 31.5-levels and my bevel (tilt of blade) to 34-levels.

The premier piece of crown molding, running together the best of the cornice box, has 2 outside corners.

The left-hand mitered outside corner is lower by placing the crown to the right of the blade. The best edge of the crown rests up towards the fence. The miter angle on the table of your miter saw is established to the right of heart.

You will also lower the right-hand side piece of crown this way. The edge of the side piece of crown that fulfills the entrance piece of crown will be lower at an angle. The other side will be flush towards the wall, so it’s a straight-edge lower.

When chopping crown, I constantly increase a 50 %-inch or a minimal extra to the overall length I measured in advance of chopping. I’ll do a examination in shape after generating my first lower and then trim a minimal extra off if I have to have to, but with crown, at the time you lower it too small, you’re out of luck! So I’m constantly extremely, extremely watchful and get my time to be guaranteed to get it right. Preserve in mind, too, that crown has to lengthen a little bit previous the length of your cornice box. If the lower edge of the crown strains up specifically with the edge of the cornice box, there will not be ample of an edge left on the crown to meet up with the edge of the side piece of crown, which you will want it to do in buy to get a neat corner.

Move 3: Assemble the Wood Cornice

I drilled holes working with my Kreg Jig together the best, inside edges of my entrance box piece and my 2 side box parts. (If you really don’t very own a Kreg Jig, you can join your box together by first gluing with wood glue and then working with ending nails or a nail gun.)

I applied wood glue to join the mitered edges of my side box parts and my entrance box piece and clamped it all to dry. Then, I applied my eighteen-gauge nail gun to strengthen the bond by nailing the parts together (you could also use a hammer and ending nails, if you really don’t have a nail gun).

Move 4: Connect 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 ending nails and a hammer). You can glue first, too, if you’d like to.

Before attaching any trim, even though, examination the in shape of your corner parts to make guaranteed they in shape together appropriately. how to build a DIY wood window cornice, solid wood window valance box

Make measured marks all together the length of your box wherever you want your crown molding to be. Then, use a degree or other straight edge to connect the marks so you have a line together which to line up the base edge of your crown molding—you want it to be degree. Nail together the base edge of your crown to attach it to your cornice box. It can be any place on the box frame you decide on for it to be—-flush with the best edge of the box or someplace farther down the box. I selected to have a 5-one/2″ gap in between the best of my ogee trim and the base of my crown molding.

You can constantly increase a shelf to the best of the cornice box, which would give the crown some thing to attach to (like it would if it had been getting fitted together a wall and ceiling), but considering the fact that on this cornice, I selected not to increase a shelf, I had to glue the corner crown parts to the heart crown piece to attach them.

Use painter’s tape to secure the relationship until finally the glue dries. Connect the base of the side parts of crown with nails together the base edge, just as you did with the entrance piece of crown.

I would advise towards making an attempt to nail the best piece of the side crown to the best piece of the entrance crown, as you’ll risk splitting the crown.

I applied a single coat of primer and two coats of paint, allowing every little thing dry extensively in between coats.

Keep in mind to paint the underside of your cornice box, too, as it will be noticeable if somebody is standing near to, or less than, the window.

If the best of your cornice box will be noticeable, be guaranteed to paint the best, too, but most of the time, a cornice box will be so near to the ceiling that no a single will be capable to see the best of it.

How to Cling a Wood Window Cornice

Slice a 1″ x 2″ strip of wood just shorter than the total length of your done cornice box.

Mount it to the wall over the window wherever you will be hanging the cornice, working with a degree and 2″ wood screws. Be guaranteed to attach to studs and not just dry wall.

Preserve in mind how much down more than your window you want your cornice to hang—-that will identify wherever on the wall you set up the 1″ x 2″ strip of wood (your cornice box will ‘hang’ on this strip of wood).

You will attach 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 over your window. It will not be secure ample to just ‘hang’ the cornice box on the 1″ x 2″ strip. You have to have to screw down by means of the best of the cornice box, in to the 1″ x 2″ strip at standard intervals together the length of the cornice box.

To make the work simpler, I screwed my 2″ wood screws partly in to the best of my cornice box in advance of hanging it, so that I’d have considerably less screwing to do after putting the cornice box in location more than the window. Be mindful in the placement of your screws. You really don’t want them so near to the edge that the wood splits, thus compromising the attachment. Neither do you really don’t want them so much absent from the edge that they will not screw down in to the best of your wall-mounted 1″ x 2″ strip.
