What Piping Is and Why You'd Use It

Piping is a narrow strip of fabric—usually folded and sewn into a cord—that you stitch into a seam to create a finished, decorative edge. You see it on pillows, cushion edges, necklines, and armholes. It's both practical and decorative: it reinforces seams and gives your project a professional, tailored look.

Piping comes in two forms. Pre-made piping is already folded and corded, ready to sew into a seam—the fastest route if you're new to this. Homemade piping means you fold and sew your own fabric strips around a cord. Homemade piping lets you match your fabric exactly, but it takes more time and practice.

Most home sewers start with pre-made piping because it's forgiving and produces reliable results. Once you're comfortable with the technique, making your own piping opens up color and pattern options that pre-made versions don't offer.

Key Takeaways

  • Pre-made piping is sewn into a seam between two fabric pieces using a piping or zipper foot, with the raw edge of the piping aligned to the raw edge of the fabric.
  • You stitch piping to one fabric piece first, then layer the second piece on top and sew through all layers, trapping the piping inside the seam.
  • Corners require clipping the piping seam allowance and pivoting your needle to turn smoothly without puckering.
  • A piping foot (or zipper foot) keeps your needle close to the cord so the finished edge sits right at the seam line.
  • Homemade piping uses bias-cut fabric strips wrapped around cord and sewn closed, then inserted the same way as pre-made piping.

Gathering Your Materials and Tools

You'll need pre-made piping (available at fabric stores by the yard), two pieces of fabric you're joining, thread that matches your piping or fabric, and a sewing machine. A piping foot is the single most useful tool—it has a groove on the bottom that rides over the cord, keeping your needle at the right distance. If you don't have a piping foot, a zipper foot works as a substitute, though it's slightly less precise.

For homemade piping, add bias tape (or fabric cut on the bias), cord (usually #2 or #3 weight cotton piping cord from a fabric store), and a bias tape maker if you want perfectly even folds. You can fold bias strips by hand, but a bias tape maker saves time and frustration.

Test your setup on scrap fabric first. Sew a short seam with piping between two scraps, then open it up and look at how the piping sits. If it's buried in the seam or sticking out unevenly, adjust your foot position or needle placement before you start your real project.

Sewing Pre-Made Piping Into a Seam

Start by pinning piping to the right side of your first fabric piece, with the raw edge of the piping aligned to the raw edge of the fabric. The piping's folded edge should face inward (toward the fabric), and the cord should sit just inside the seam allowance. Pin every 2 to 3 inches, and use a few pins at corners to hold the piping in place while you work.

Attach your piping foot to your machine and thread it with matching thread. Lower the presser foot and position your needle so it runs along the piping cord—not through the cord itself, but right next to it. Sew slowly, keeping the piping straight and the cord centered in your foot's groove. Backstitch at the start and end of each seam.

Once piping is sewn to the first piece, place your second fabric piece on top, right sides together, and pin it in place. The piping is now sandwiched between the two pieces. Sew along the same line you just stitched, using the piping foot again. This second seam locks the piping inside the seam and creates the finished edge you see on the outside.

Open up your pieces and press gently. The piping should sit right at the seam line, with the cord visible and the fabric edges hidden inside. If the piping is buried or loose, you may need to adjust your needle position on the next seam.

Turning Corners and Curves Smoothly

Corners are where piping can pucker or bunch if you're not careful. As you approach a corner, sew to within about half an inch of the corner point. Stop with the needle down, raise the presser foot, and clip the seam allowance of the piping—just the raw edge, not the cord—at a 45-degree angle. This small cut lets the piping fold without bunching.

Pivot your fabric and presser foot around the needle, then lower the foot and continue sewing along the next edge. The clipped seam allowance will spread slightly as you turn, and the piping will fold neatly at the corner. Practice this on scrap fabric first; it feels awkward until you've done it two or three times.

For gentle curves, you don't need to clip. Just sew slowly and let the piping ease around the curve naturally. Tight curves (like a small armhole) may need one or two small clips to prevent puckering, but most home sewing projects have gentle enough curves that clipping isn't necessary.

Making Your Own Piping from Scratch

Cut fabric strips on the bias (at a 45-degree angle to the grain) and sew them end-to-end to create one long strip. The bias direction lets the fabric fold smoothly around curves without bunching. Fold the strip in half lengthwise, wrong sides together, and press with an iron to create a crease down the middle.

Lay your cord along the crease inside the folded strip. Using a piping foot or zipper foot, sew close to the cord to encase it in fabric. The stitching line should run along the inside fold, not through the cord. Trim the raw edges to an even width—usually about half an inch—so they align with your seam allowance.

Once your piping is made, insert it into seams the same way you would pre-made piping. The advantage is that your piping matches your fabric exactly. The disadvantage is that homemade piping takes time, and mistakes in cutting or sewing the bias strip show up in the finished seam. Most sewers make homemade piping only when they can't find a pre-made color or pattern that works.

Fixing Common Piping Problems

If your piping is buried in the seam and invisible from the outside, your needle was too far from the cord when you stitched. On your next project, move the needle closer to the cord. If the cord is sticking out and the fabric edge is visible, your needle was too close. Small adjustments to needle position make a big difference.

Puckering at corners usually means you didn't clip the seam allowance deeply enough. Next time, make a slightly deeper cut—you won't hurt the piping itself, only the raw edge that gets hidden in the seam. If piping twists or spirals as you sew, you're pulling it too tight as you pin. Pin more loosely and let the piping sit naturally along the seam line.

If your thread shows on the finished seam, switch to thread that matches the piping fabric, not your main fabric. If you're using pre-made piping in a contrasting color, matching thread to the piping keeps the stitching line less obvious.

When to Call a Professional Tailor

Piping is a learnable skill, and mistakes on practice projects don't ruin anything—you can always rip out stitches and try again. However, if you're adding piping to a garment you've already invested time in, or to an expensive fabric, consider having a tailor do it. A professional can match piping to your fabric, handle tricky curves or multiple corners, and may provide the result looks polished.

Tailors charge by the yard of piping or by the hour, depending on the complexity. A straightforward pillowcase with piping on one edge might cost $15 to $30; a jacket with piping on the neckline, armholes, and front edges could run $50 to $100 or more. Get a quote before you commit.

Frequently Asked Questions

Can I use regular presser foot instead of a piping foot?

Yes, but it's harder to keep the stitching line consistent. A regular foot doesn't have a groove to guide the cord, so your needle position can drift. A zipper foot is a better substitute than a regular foot because it's narrower and lets you sew closer to the cord. A piping foot is worth buying if you plan to make more than one or two piped projects.

What happens if I sew piping on backwards?

The cord will be on the outside of the seam instead of hidden inside, and the fabric edge will be visible. It's not wrong—some sewers do this intentionally for a decorative effect—but it's not the traditional look. If you catch it before you sew the second piece on, just rip out the stitches and flip the piping around.

Do I need to pre-wash piping before I use it?

Pre-made piping usually doesn't need pre-washing because the cord is already preshrunk. If you're making your own piping from fabric scraps, wash and dry the fabric first so it shrinks before you cut and sew. This prevents the finished piping from puckering after your project is washed.

How do I join two ends of piping at the same point?

Overlap the ends by about an inch, sew through both layers, then trim the excess. The overlap creates a thick spot in the seam, so this works best on seams that won't get heavy wear. For a neater join, cut the cord inside each piping end, overlap the fabric shells, and hand-stitch them closed before inserting into the seam—but this takes practice and patience.

Can I use piping on knit fabrics?

Yes, but use a ballpoint needle and a stretch stitch on your machine to keep the seam from breaking when the fabric stretches. Knits are more forgiving than wovens, so piping often looks great on them. Test on a scrap first to make sure your seam has enough give.
