What You're Building and Why the Order Matters

A roman shade is a window covering that folds up in horizontal pleats when you pull a cord, then hangs flat when you lower it. Unlike a roller shade, it's made from fabric you choose and sew yourself, so you control the look, weight, and lining. The shade works because of a rod pocket sewn into the back—wooden dowels or rods sit in these pockets and create the fold lines. When you pull the lift cords threaded through rings on the back, the rods stack on top of each other and the shade rises.

The construction order matters because each step depends on the one before. You'll cut and prepare your fabric first, then sew the side seams and rod pockets, add the lining, install the hardware, and finally thread the cords. If you skip steps or reverse them, you'll end up ripping seams or having to start over.

Key Takeaways

  • Measure your window opening width and decide how far down the shade should hang, then add 2 inches to the width and 3 inches to the length for seam allowances and hems.
  • Sew the side seams first, then the bottom hem, then sew the rod pockets on the back using a ruler to space them evenly—usually 4 to 6 inches apart depending on your fabric weight.
  • Attach the lining to the back of the shade with fabric glue or by hand-stitching, which hides the rod pockets and gives the shade a finished look from outside.
  • Mount the shade to the wall or window frame using a wooden mounting board, then install the hardware (rings, cord, and pulley) on the back before threading the cords through.
  • Test the shade by pulling the cord gently before you trim the excess cord, because a snag or knot in the threading will jam the whole mechanism.

Measuring Your Window and Calculating Fabric Size

Start by measuring the width of your window opening from the inside of the frame, from one side to the other. Write this number down. Then decide how far down you want the shade to hang—most people choose to the windowsill, to the bottom of the frame, or 4 to 6 inches below the frame. Measure that distance from the top of the opening to your chosen endpoint and write it down too.

Add 2 inches to the width (1 inch on each side for seam allowance) and 3 inches to the length (1 inch at the top for the mounting board attachment, 2 inches at the bottom for the hem). That's your cut size. For example, a 36-inch-wide window with a 48-inch drop becomes 38 inches wide by 51 inches long when you cut it.

Buy fabric that is at least as wide as your cut width—if your shade is wider than standard fabric, you'll need to sew two pieces together along the length. Linen, cotton, linen-cotton blends, and lightweight canvas work well. Avoid stretchy fabrics and very heavy upholstery fabric for your first shade, because they're harder to control.

Sewing the Side Seams and Bottom Hem

Cut your fashion fabric (the fabric you see from outside) to size. Place it wrong side up on your work surface. Fold one long edge over by 1 inch, press it with an iron, and pin it. Sew this fold down with a straight stitch about ¼ inch from the fold. Repeat on the other long edge. These are your side seams, and they finish the raw edges so the shade won't fray.

Now fold the bottom edge up by 2 inches, press it, and pin it. Sew this fold down ¼ inch from the fold. This is your bottom hem. Press all three seams flat with the iron when you're done.

Lay the shade flat again, wrong side up. Measure down from the top edge and mark where you want your first rod pocket to sit—usually 3 to 4 inches down. Use a ruler and a fabric pencil or chalk to draw a light line all the way across. Then mark the next line 4 to 6 inches below that, and keep going until you're about 4 inches from the bottom hem. These lines are where you'll sew the rod pockets.

Sewing Rod Pockets on the Back

The rod pocket is a channel sewn into the back of the shade that holds the wooden dowel or rod. To make one, you sew two parallel lines close together, creating a tunnel between them. The space between the lines should be about ½ inch wider than your dowel—so if you're using a ½-inch dowel, make the pocket about 1 inch wide.

Using your marked lines as a guide, sew the first line of the first pocket. Then move your presser foot over about 1 inch and sew the second line parallel to the first. Repeat this for every marked line. Sew slowly and use a ruler under the presser foot to keep the lines straight. When you're done, you'll have a series of channels running across the back of the shade.

Slide a wooden dowel or rod into each pocket to test the fit. It should slide in smoothly without forcing. If it's too tight, you may have sewn the pocket too narrow—you can carefully cut a small slit in the lining later to widen it, but it's better to get it right the first time.

Attaching the Lining

The lining goes on the back of the shade and serves two purposes: it hides the rod pockets and the rings from the outside, and it adds weight and structure so the shade hangs evenly. Cut lining fabric to the same size as your fashion fabric (before you added seams). Lay the shade wrong side up, then lay the lining on top of it, also wrong side up, so the two right sides face each other.

You can attach the lining by sewing it around three sides (leaving the top open) and then turning the whole thing right side out, or you can glue it down with fabric glue. The sewing method is more durable but takes longer. If you sew, use a ¼-inch seam allowance, leave a 4-inch opening at the top, turn it right side out through that opening, and hand-stitch the opening closed. If you glue, spread a thin, even layer of fabric glue across the back of the shade and press the lining down, smoothing out air bubbles as you go.

Once the lining is attached, press the whole shade flat with an iron on low heat. The lining should be smooth and flat against the back, with no wrinkles or bunches.

Installing Hardware and Threading the Cords

You'll need a wooden mounting board (a 1-by-2 or 1-by-3 board cut to the width of your shade), a set of roman shade rings (small plastic or metal rings that attach to the back of the shade), a cord (usually nylon or cotton, sold in rolls), and a pulley or cleat (the hardware that holds the cord when the shade is raised). These are sold as roman shade kits at fabric and hardware stores.

Attach the rings to the back of the shade by sewing them on by hand or using a needle and thread. Space them vertically in columns—usually one column every 12 to 18 inches across the width of the shade, and one ring in each rod pocket. The rings need to line up perfectly vertically, so use a ruler and mark their positions before you sew.

Mount the shade to the wall or window frame by screwing the mounting board to the studs or frame. Attach the pulley to one end of the board (usually the right side, but you can choose). Thread the cord through the rings, starting at the bottom ring on the left, going up through all the rings in that column, then across through the pulley, and down the side of the shade. Repeat for each column of rings, so all cords end up running down the right side of the shade and through the pulley.

Tie a knot at the end of each cord and trim the excess. Test the shade by pulling the cord gently—it should rise smoothly and evenly. If one side rises faster than the other, the cords may not be threaded evenly through the rings. Adjust by loosening the knots, re-threading, and testing again.

Troubleshooting Common Sewing Problems

If your rod pockets are uneven or wavy, you likely sewed them without a guide. Use a ruler under the presser foot next time, or mark your lines with a fabric pencil and sew slowly. If the shade doesn't hang flat, the lining may not be attached evenly—smooth it out and re-glue or re-stitch any loose spots.

If the shade pulls to one side when you raise it, the cords are not threaded evenly through the rings. This is the most common problem and is fixable by re-threading. If the shade gets stuck halfway up, there's likely a knot or snag in one of the cords—pull the cord out gently and check for tangles before threading it back through.

If you sewed the rod pockets too narrow and the dowel won't fit, you can carefully cut a small slit in the lining along one of the pocket seams, widen the pocket by hand, and then hand-stitch the lining closed. This is tedious, so measure twice before you sew the first time.

Frequently Asked Questions

Can I use regular curtain fabric for a roman shade?

Yes. Lightweight to medium-weight cotton, linen, and linen blends work well. Avoid very stretchy knits or heavy upholstery fabric—they don't fold evenly and are hard to sew by hand. Test a small piece by folding it to see how it creases.

What size dowel should I use for the rod pockets?

A ½-inch wooden dowel is standard and works for most home sewn shades. If your fabric is very heavy, a ⅝-inch dowel adds more support. Dowels are sold at hardware stores in 36-inch lengths and cost a few dollars each.

Do I have to use a lining?

No, but it's worth it. Lining hides the rod pockets and rings from outside, gives the shade a more finished look, and adds weight so it hangs evenly. Without lining, the back of your shade will show all the hardware and may look homemade.

How do I clean a roman shade after I've sewn it?

Dust it with a soft brush or vacuum with an upholstery attachment. If it needs washing, check your fabric care label. Most cotton and linen shades can be hand-washed in cool water and laid flat to dry, but test a corner first. Do not machine wash or dry, because the cords and rings can snag.

What if my window is wider than standard fabric width?

You'll need to sew two pieces of fabric together lengthwise (along the long edge) to make it wide enough. Use a ½-inch seam allowance and press the seam open. Match any pattern before you sew so the seam is invisible. This adds one seam to the front of the shade, so choose a fabric where a vertical seam won't be noticeable.
