The basic method: attaching a cuff with a machine

A cuff is sewn to a sleeve in two stages: first you stitch the cuff to the sleeve opening, then you fold the cuff over and stitch it down from the inside. The cuff itself is usually a rectangle of fabric, often interfaced (reinforced with a backing layer) to hold its shape. You will need the sleeve already sewn into the garment, or at least sewn into a tube, and the cuff cut to the right width and length.

Start by pinning the cuff to the right side of the sleeve opening, with the raw edges aligned. The cuff should wrap around the sleeve opening with a small overlap at the seam where the sleeve was joined. Sew along the pinned line using a straight stitch, usually 5/8 inch from the edge. Press the seam open with an iron, then fold the cuff down and press again so the fold is crisp.

Fold the raw edge of the cuff inward by about 1/4 inch and press. Now fold the cuff up and over the seam you just made, so the folded edge covers the stitching line. Pin it in place from the inside of the sleeve. Stitch along the fold using a straight stitch or a topstitch (a visible stitch that runs parallel to the edge). This second row of stitching holds the cuff permanently in place.

Key Takeaways

  • A cuff is attached in two stages: first stitching it to the right side of the sleeve, then folding it over and stitching from the inside to cover the seam.
  • The cuff should be cut as a rectangle, usually interfaced for stiffness, and wrapped around the sleeve opening with a small overlap at the seam.
  • Pressing with an iron at each stage—after the first seam, after folding, and after the final stitch—keeps the cuff crisp and even.
  • The second row of stitching can be a straight stitch hidden on the inside or a topstitch visible on the outside, depending on the look you want.

Preparing the cuff before you attach it

Before you pin the cuff to the sleeve, the cuff itself needs to be prepared. Cut a rectangle of fabric to the width you want the finished cuff to be (usually 1.5 to 2 inches), plus 1.25 inches for seam allowances. The length should be the measurement around the sleeve opening plus 1 inch for overlap at the seam.

If you are using interfacing, cut a piece the same size as your cuff fabric and fuse it to the wrong side using an iron and the heat setting recommended on the interfacing package. This stiffens the cuff so it holds its shape. Then fold the cuff in half lengthwise, wrong sides together, and press. You now have a cuff that is folded and ready to attach.

Some sewers prefer to sew the cuff into a loop before attaching it to the sleeve. To do this, fold the cuff in half lengthwise (right sides together), sew the short ends together with a 5/8-inch seam, and press the seam open. Then turn the cuff right side out, fold it in half again, and press. This method gives you a cuff with no visible seams at the overlap.

Measuring and pinning the cuff to the sleeve opening

Measure around the sleeve opening at the point where you want the cuff to sit. This is usually about 1/2 inch from the raw edge of the sleeve. Write down this measurement. Your cuff length should be this measurement plus 1 inch for the overlap.

Pin the cuff to the right side of the sleeve opening, starting at the sleeve seam. Align the raw edges of the cuff with the raw edge of the sleeve. Distribute the fabric evenly around the opening so there are no bunches or gaps. The overlap should fall at the sleeve seam, where the two ends of the cuff meet. Use plenty of pins—one every inch or so—to keep the cuff from shifting while you sew.

If the sleeve opening is slightly larger than your cuff, you may need to ease the sleeve fabric onto the cuff. This means gently gathering the sleeve fabric as you pin so it fits the cuff length. Sew slowly and let the presser foot feed the fabric evenly. If the cuff is much larger than the sleeve opening, you have measured wrong; take out the pins and remeasure.

Stitching the cuff to the sleeve and pressing

Sew the cuff to the sleeve using a straight stitch with a 5/8-inch seam allowance. Start at the overlap point and sew all the way around the sleeve opening, removing pins as you go. Sew slowly so you can keep the seam straight and the cuff from shifting. When you reach the starting point, overlap the stitches by about 1/2 inch and cut the thread.

Press the seam open with an iron on a medium heat setting. Place the sleeve on the ironing board with the seam facing up, and press the seam flat so it lies on both sides of the stitching line. This reduces bulk and makes the cuff lie flat. Then fold the cuff down away from the sleeve and press again, creating a sharp fold at the edge of the cuff.

Trim the seam allowance if it is very thick—you can cut it down to 1/4 inch to reduce bulk. This is especially important if you used interfacing, which adds thickness. Be careful not to cut into the cuff itself or the sleeve.

Folding and stitching the cuff from the inside

Fold the raw edge of the cuff inward by about 1/4 inch and press it with an iron. This creates a finished edge that will not fray. Now fold the cuff up and over the seam you just made, so the folded edge sits just over the line of stitching. Pin it in place from the inside of the sleeve, using pins that go through all layers.

Stitch along the fold using a straight stitch. You can sew from the inside of the sleeve (so the stitching is hidden) or from the outside (so the stitching is visible as a topstitch). If you sew from the inside, use a needle and thread that match the cuff fabric. If you topstitch from the outside, you can use a contrasting thread for a decorative look. Sew slowly and keep the stitching line parallel to the fold.

Remove all pins and press the finished cuff with an iron. The cuff should now be smooth, even, and permanently attached to the sleeve. If you see any puckering or unevenness, you can carefully remove the stitches with a seam ripper and re-sew.

Variations: ribbed cuffs and elastic cuffs

A ribbed cuff is made from ribbed knit fabric, which stretches and recovers. Ribbed cuffs are common on knit garments like t-shirts and sweatshirts. Measure the sleeve opening and cut the ribbed fabric to about 70 to 80 percent of that measurement, so the cuff will stretch slightly when you wear it. Sew the short ends of the ribbed fabric together to form a loop, then fold it in half lengthwise and attach it to the sleeve using a stretch stitch or a narrow zigzag stitch. The stretch in the fabric allows the cuff to move with your arm.

An elastic cuff has elastic sewn into the hem to make it gather and hold snugly. Cut a cuff to the desired width and length, then sew elastic to the wrong side of the cuff using a zigzag stitch. The elastic should be slightly shorter than the cuff so it gathers the fabric. Attach the cuff to the sleeve as you would a regular cuff, but use a stretch stitch to allow the elastic to move.

Both of these variations follow the same two-stage method: attach the cuff to the right side of the sleeve, then fold it over and stitch from the inside. The main difference is the fabric you use and the stitch you choose to accommodate stretch.

Troubleshooting common cuff problems

If your cuff is puckered or wavy, the seam allowance is probably too large or the cuff was not eased evenly onto the sleeve. Remove the stitches with a seam ripper, trim the seam allowance to 1/4 inch, and re-sew more slowly, distributing the fabric evenly. Press again with an iron.

If the cuff is loose or slides around, you may not have pinned it tightly enough or the seam allowance shifted while you sewed. Remove the stitches and re-pin, using more pins and checking that the raw edges are aligned all the way around. Sew again, holding the cuff steady with your hands as you feed it under the presser foot.

If the second row of stitching is visible from the outside when you wanted it hidden, you sewed too far from the fold. The stitching line should sit just barely over the seam line so it is covered by the fold of the cuff. Remove the stitches and sew again, moving the line closer to the fold.

Frequently Asked Questions

Can I attach a cuff to a sleeve that is already sewn into the garment?

Yes. The cuff attaches to the sleeve opening, which is the raw edge at the wrist or arm opening. You can attach it whether the sleeve is sewn into the garment or still a flat piece. If the sleeve is already sewn in, you will be working in a small space, so use a narrow presser foot or a cuff foot (a special presser foot made for this task) to help you sew evenly.

What is the difference between a cuff and a hem?

A cuff is a separate piece of fabric sewn to the edge of a sleeve, while a hem is the edge of the sleeve fabric itself, folded and stitched. A cuff is thicker and more structured, while a hem is simpler and flatter. Cuffs are common on woven garments like shirts, while hems are common on knit garments like t-shirts.

Do I need interfacing in a cuff?

Interfacing is not required, but it helps the cuff hold its shape and look crisp. If you are making a casual garment or a cuff from a stiff fabric like denim, you may not need interfacing. If you are making a dress shirt or a cuff from a soft fabric like cotton, interfacing will make the cuff look more polished.

How do I attach a cuff to a stretchy knit sleeve?

Use a stretch stitch or a narrow zigzag stitch instead of a straight stitch. This allows the seam to stretch with the fabric so it does not break when you move. You can also use a ribbed cuff, which is designed to stretch. Measure the sleeve opening and cut the ribbed cuff to about 70 to 80 percent of that measurement so it will stretch when you put the garment on.

What if my cuff is too long or too short?

If the cuff is too long, you can trim the overlap before you attach it. If the cuff is too short, you will need to cut a new cuff. Measure the sleeve opening again and add 1 inch for the overlap. If you have already attached the cuff and it is wrong, remove the stitches with a seam ripper, take off the cuff, and start over with a new piece of fabric cut to the correct length.
