Step 1

Lay Fabric on Flat Work Surface

Start by spreading the fabric out, cutting the flat sheet cleanly in half lengthwise. If you’re using a plain sheet and want to add a personal touch, consider stenciling for added appeal.

Pro Tip

All of my measurements will vary from yours, because mine are made straight to the size of the bedroom window, but this concept can be carried out in almost any size. 

Top to bottom, I only needed a 50″ length for each window, and the bolt of blackout fabric measured 54″ wide, so I was essentially able to buy two yards of fabric (totalled $7.50!) and cut it width-wise to fit both windows. Had I not realized this at the store, I would have brought home fabric to length (almost 4 yards) and had a lot leftover.

Step 2

Position the Blackout Fabric

On top of that, I overlaid a yard of the blackout curtain (I had the store cut my two yards into two pieces for convenience).

Step 3

Attach Fabric to Header Board

I used the miter saw to cut the 6-foot board in half; I sized my curtains to be 36″ in width, and each one would require a header board that could support the weight of the curtain, and be attached easily to the wall. As shown on one curtain here, I used the electric staple gun to attach both layers of fabric directly to the board.

Step 4

Attach Plastic Rings to Fabric

I sewed plastic rings up and down both sides of the shade and along the top beneath the wooden header, spacing them about 15″ apart.

Step 5

Fuse Fabrics With Sewing Bond

Use Stitch Witchery (the common 5/8″ wide variety) to fuse the two fabrics together. Not shown but eluded to in the previous image, I also used the Stitch Witchery to seal in a dowel at the bottom of the curtain to give the base a little weight and help it to hang evenly.

Step 6

Assemble Pull Strings

Thread a thin but strong nylon rope through the rings.

Step 7


The easiest and safest installation I brainstormed was to screw the wooden header directly into the window frame, but I did so by hiding the screws beneath the fabric layers so that it retained its finished appearance.

I added a little hook to the wall to anchor the weight of the curtain when it’s raised, and it’s high enough off the ground where there’s no worry about a kid accidentally tangling themselves in it.

Pro Tip

If you have is a little sag in the middle of the shade, you may want to add an additional row of plastic rings down the middle of the shade to guide a third string (I imagine that if you are covering a window any wider than 36″ you will want to take this into consideration upfront).
