Sewing ruffle trim is a hand or machine stitch that attaches a gathered or pleated edge to a garment or project

Ruffle trim adds texture and movement to clothing, pillows, curtains, and quilts. The trim itself is already gathered or pleated—you are straightforward fastening it to your base fabric with a straight stitch, either by hand or machine. The most common method is to sandwich the ruffle between two layers of fabric (the garment and a facing or binding), then stitch through all three layers at once. This hides the raw edge of the ruffle and creates a clean, finished look.

The key to success is pinning the ruffle evenly before you stitch, keeping tension consistent as you sew, and choosing thread that matches either the ruffle or the garment. Most sewers complete this task in 15 to 45 minutes, depending on the length of the trim and whether you use a machine or hand-stitch.

Key Takeaways

  • Ruffle trim is attached by stitching it between the garment fabric and a facing or binding layer, which hides the raw edges.
  • Pin the ruffle in place before sewing, spacing pins every 2 to 3 inches to keep the gathers even and prevent bunching.
  • Use a straight stitch on your machine set to medium length (2.0 to 2.5 mm), or hand-stitch with a running stitch about 1/8 inch from the edge.
  • Sew slowly and keep even tension on the fabric to avoid puckering or stretching the ruffle out of shape.
  • Press the seam flat after stitching to set the stitch and create a professional finish.

Prepare the ruffle trim and garment pieces

Before you begin sewing, lay out all the pieces you will need: the ruffle trim, the main garment piece, and the facing or binding that will cover the seam. If your ruffle trim has a raw edge on one side, trim it straight with scissors or a rotary cutter so it is even. Measure the length of the edge where the ruffle will go and make sure your ruffle trim is at least that long—ruffles compress when sewn, so having extra length gives you room to adjust.

Press the garment piece and the facing with an iron on a low to medium heat setting. A smooth, flat surface makes pinning much easier and prevents wrinkles from being sewn into the seam. If the facing is a separate piece (like bias tape or a strip of fabric), press it as well. Do not press the ruffle itself—the gathers are intentional, and pressing will flatten them.

Pin the ruffle in place along the edge

Lay the garment piece flat on your work surface with the right side facing up. Position the ruffle trim along the edge where it will be attached, with the gathered or pleated edge pointing outward (away from the garment). The raw edge of the ruffle should sit on top of the raw edge of the garment, aligned so they are even.

Starting at one end, insert a pin through the ruffle and into the garment, perpendicular to the edge. Space pins every 2 to 3 inches along the entire length. As you pin, gently spread the gathers so they are distributed evenly—do not bunch them all in one spot. If the ruffle is longer than the edge of the garment, ease it in by gathering the fabric slightly as you pin, so the ruffle lies flat without puckering.

Check that the ruffle is not twisted and that the gathers run parallel to the edge of the garment. Twisted ruffles will look crooked when the seam is finished.

Stitch the ruffle between the garment and facing

Place the facing or binding strip on top of the pinned ruffle, with the right side of the facing facing down (toward the ruffle). The ruffle is now sandwiched between the garment and the facing. Pin the three layers together, using the existing pins as a guide and adding more as needed to hold the facing in place.

If you are using a sewing machine, set the stitch length to 2.0 to 2.5 mm (a medium length that is small enough to hold the ruffle securely but not so small that it puckers the fabric). Thread the machine with thread that matches the garment or the ruffle—either choice works, as long as the thread color blends. Position the needle about 1/4 inch from the raw edges of the ruffle and garment, and sew slowly along the entire length. Keep your hands relaxed and let the machine feed the fabric; do not pull or push.

If you are hand-stitching, use a running stitch with stitches about 1/8 inch long and 1/8 inch apart. Start at one end and work toward the other, keeping the needle perpendicular to the edge and maintaining even tension. Hand-stitching takes longer but gives you more control over how the ruffle sits as you work.

Trim and finish the seam

Once you have stitched the entire length, remove the pins and trim the raw edges of the ruffle and garment to about 1/4 inch from the seam line. Use sharp scissors or a rotary cutter for a clean cut. If the fabric frays easily (like cotton or linen), consider finishing the raw edges with a zigzag stitch on your machine or by hand with a whip stitch.

Press the seam flat with an iron on a medium heat setting, pressing from the facing side. This sets the stitch and flattens the seam allowance. If the facing is a separate piece, fold it to the back of the garment and press again. The ruffle should now sit neatly along the edge, with no raw edges visible from the front.

Common mistakes to avoid

The most frequent error is sewing the ruffle on without a facing, which leaves the raw edge of the ruffle visible and unfinished. Always sandwich the ruffle between two layers. Another common mistake is bunching the gathers in one spot instead of spreading them evenly—this creates an uneven, lumpy appearance. Take time to distribute the gathers as you pin.

Pulling the fabric as you sew will stretch the ruffle out of shape and cause puckering. Let the machine do the work, or move your hand slowly and steadily if you are hand-stitching. Sewing too fast also increases the risk of skipped stitches or uneven seams. Finally, do not skip pressing the seam after stitching—a pressed seam looks professional and helps the ruffle sit flat.

Choosing thread and needle for your project

Match your thread color to the garment or the ruffle, whichever is more visible in the finished project. If the ruffle is a contrasting color, thread that matches the garment usually blends better. For machine sewing, use all-purpose polyester or cotton thread in a weight appropriate to your fabric—lightweight thread for delicate fabrics, standard weight for cotton and linen.

Choose a needle size based on your fabric weight: a size 60/8 or 70/10 needle for lightweight fabrics, a 80/12 for medium-weight fabrics, and a 90/14 for heavier fabrics. A needle that is too small will break; one that is too large will leave visible holes. If you are hand-stitching, use a needle that is comfortable to hold and small enough to pass through the fabric without effort.

Frequently Asked Questions

Can I attach ruffle trim without a facing?

Technically yes, but the raw edge of the ruffle will be visible and will fray over time. A facing or binding hides the raw edge and creates a finished look. If you do not want to add a facing, you can fold the raw edge of the ruffle to the back and stitch it down, but this is more work than using a facing strip.

What if my ruffle trim is too short for the edge?

Measure again to be sure. If the trim is genuinely too short, you can sew multiple pieces end-to-end before attaching them to the garment, or you can explore the ruffle to only part of the edge (like one side of a neckline). Avoid stretching the ruffle to fit, as this will cause it to pucker when the garment is worn.

How do I keep the ruffle from bunching when I sew?

Pin it every 2 to 3 inches and spread the gathers evenly as you go. Sew slowly and do not pull the fabric. If bunching still happens, you may be sewing too fast or the gathers are not distributed evenly before you start. Unpick the seam, repin, and try again.

Should I use a walking foot for ruffle trim?

A walking foot helps feed multiple layers of fabric evenly and can reduce puckering, especially on delicate fabrics or when sewing through three layers. It is not required, but it is useful if you find that the layers are shifting as you sew.

Can I machine-wash a garment with ruffle trim?

Yes, as long as the trim and garment are made from washable fabric and the seam is find. Wash on a gentle cycle in cool water and air-dry to protect the gathers. Avoid high heat in the dryer, which can damage the trim and set wrinkles into the gathers.
