How to Build an Old Window Frame using Lumber

Easy to Make Old Window Frame Backdrop Project

Thankfully Summer is still here and I am loving the time outdoors building simple things and enjoying every ray of sunshine. Unfortunately, lazy summer days don’t last forever and before we know it Fall and Halloween decorating seasons will be here. This year I am finally getting a bit of a head start by making background decor items when I still have time. The first of these is this old window frame project.

There are so many gorgeous examples of home decor using old window frames, I love all the different old window crafts and window frame ideas. Unfortunately, there are not many old pane windows available where I live and if you do find one, they come with an antique price.

Its also much less work to build one of your own then it is to try and find an affordable one in the architectural resale places or buy one online. In addition, this one weighs less than half of a real window as there is no glass, and the wood is less than an inch thick.

My youngest son decided to hang out in the garage with me, and even with visiting and figuring out what leftover wood we could use it took us less than two hours to build the window frame and if you have to buy the lumber etc, I guesstimate the cost at under $20 for this three by four foot  large window frame.

Supplies for Building an Old Window Frame

2 – pieces of 1 by 6 lumber 4 feet long.

2 – pieces of 1 by 6 lumber 3 feet long.

2 – pieces of 1 by 2 lumber at least 40 and 30 inches long (you will trim them to size)

4 –  L-shaped flat brackets

4 – straight flat brackets

Sandpaper 60,120, 150 grit

Wood glue, clamps and wood screws.

Old Window Frame Tutorial

Start by sanding all your lumber with 60 grit and then 120 grit sandpaper.

Cut the ends of your 1 by 6  inch lumber at 45-degree angles.

Make sure the angles are cut in the right direction so that the four pieces of lumber fit together.

Apply wood glue to the seams.

Attach the L brackets on all four corners and let dry.

Making the Panes

There are a couple of ways to do this.   Now that you have the wood frame put together, measure the opening and cut your two cross pieces to the exact length.

Find the center of the 1 by 2 .  The actual width of the 1 by 2″ board is 1.5″, so measure back from center 3/4 of an inch each way and mark with a pencil.

Using a router or a chisel, remove half the thickness of the wood between the two marks.

Alternative Method

Measure your first board and attach at the middle. Measure the distance from the edge on both sides and cut two pieces.  Glue and clamp in place,  use a straight bracket to hold the cross piece.  Fill the seams with wood putty, let dry, and sand well.

This simple project was finished using two coats of grey chalk paint, and one coat of white chalk paint.  I sanded well between each coat with  150 grit sandpaper.

I did not distress my frame,  but you most certainly can.

Using in Decor

There are so many uses for this large backdrop, it adds height to any vignette, you can hang large decor items from it, or banners, wreaths, galvanized signs, mini lights etc.  So many fun choices.

This frame was made for my fall decor, but today’s post I am posting plain pictures of it so the frame itself stands out.  I will share more images of the frame once I complete my fall mantel.  Here is  a  neutral fall home tour showing you some other ideas I have had using backdrops for fall decorating.

  1. Ah yes to this. The struggle is real. We can’t seem to find old windows here in South Africa too and when do I’d have to take out a loan to afford them 😀 Great tutorial Leanna. Thanks so much

    1. I am so glad the post helped you. I am quite startled at the comments about prices, I assumed it was regional. I guess vendors know we want them.

  2. Awesome job Leanna! And how fun to do it with your son!! I found my window on the sidewalk during a Sunday morning walk, and Sailor helped with creating the dividers and adding the chicken wire. But apparently they ARE in high demand; I have seen windows in stores with ridiculous price tags. Your ingenuity is smart ! Good for you to be starting on Fall and Halloween now; I am trying to do the same thing. I am pestering Sailor to pull down the Fall Harvest bins, and he looks at me like I have grown 2 heads! He doesn’t understand- we have a lot of work ahead of us! You bet I am pinning this !

    1. Right on Kristine. We need to get started early especially on the various backgrounds etc. From now until the end of the year we don’t really have time for extras. That was a painful lesson learned when I began blogging. Like Sailor, Hubs thinks I have lost my mind. lol

  3. I really luv this project. It has inspired me to make one for my sunroom! I’d luv to invite you to share it with us at Wall to Wall DIY Wednesday, which runs thru Mondays! Best, Ann

    1. I was under the impression that they were inexpensive where you live. I just assumed. I love the window crafts and I like how thinner this frame.
