Hand hemming works best for straightforward, straight hems on pants, skirts, and dresses

You can finish a hem entirely by hand using a needle, thread, and scissors—no machine required. Hand hemming takes longer than machine sewing (usually 20 to 45 minutes depending on the garment length), but it gives you more control and works on delicate fabrics that might jam or snag in a machine. The stitch you'll use is called a slip stitch or ladder stitch, which is nearly invisible from the outside when done correctly.

Hand hemming works best on straight hems with no curves. If you're hemming a circle skirt or something with a lot of flare, the fabric will bunch and the stitch will show. For those, a machine is faster, but a straight pant leg or straightforward A-line skirt hem is perfect for hand work.

Key Takeaways

  • Measure the desired length while wearing the garment and shoes you'll wear with it, then mark the hem line with pins or tailor's chalk.
  • Fold the raw edge up twice (about half an inch each time) to hide the frayed edge, then pin the fold in place before you start stitching.
  • Use a slip stitch, which hides inside the fold of fabric and is nearly invisible from the outside when sewn correctly.
  • Work in short segments with a single thread about 18 inches long, and re-thread rather than using one very long thread that tangles.
  • Press the finished hem with an iron on low heat to flatten the stitches and set the fold permanently.

Measure and mark the hem line before you cut anything

Put on the garment with the shoes or socks you'll actually wear with it. Stand in front of a mirror and have someone else measure from the floor to where you want the hem to end, or use a measuring tape yourself. The hem should be even all the way around—ask your helper to check the back and sides, or turn slowly in front of the mirror.

Once you know the length, take off the garment and lay it flat on a table. Measure up from the bottom edge the distance you just confirmed, and mark that line with pins placed every 2 to 3 inches around the entire garment. You can also use tailor's chalk or a fabric pencil instead of pins if you prefer. This marked line is where you'll fold the fabric to create the hem.

Fold and pin the hem in place

Fold the fabric up along your marked line and press it flat with your hands. Now fold the raw (frayed) edge up again by about half an inch, so the raw edge is hidden inside a double fold. This double fold prevents fraying and gives you a clean edge to stitch. Pin this folded edge in place every 2 to 3 inches all the way around.

If the fabric is thick (like denim or canvas), you may only need one fold instead of two—fold it up once by about three-quarters of an inch. The goal is to hide the raw edge and create a fold that's straightforward to stitch through. Press the pinned hem flat with your hands or a cool iron to set the crease before you start sewing.

Thread your needle and tie a knot

Cut a piece of thread about 18 inches long. This length is short enough to handle without tangling but long enough to stitch a good section of the hem before you need to re-thread. Match the thread color to the fabric as closely as possible—if you can't find an exact match, choose a shade slightly darker rather than lighter, because it will blend better.

Insert the thread through the eye of your needle. Pinch both ends of the thread together and tie a knot at the end. The knot should be small and tight so it doesn't pull through the fabric. If you're nervous about the knot, wrap the thread around your finger once before pulling it tight—this creates a larger knot that won't slip through.

Sew the slip stitch along the entire hem

Start at a seam or an inconspicuous spot (like the inside of a pant leg). Push the needle through the fold of fabric from the inside, so the knot stays hidden inside the fold. Bring the needle out about a quarter-inch along the fold.

Now insert the needle directly across from where it came out, into the main body of the garment (not the fold). Push it through the fabric for about a quarter-inch, then bring it back out. The needle should come out right next to where you inserted it. Now push the needle back into the fold of fabric directly across from where it just came out, and repeat this pattern all the way around the hem.

The key to an invisible stitch is keeping your stitches small and tight. Each stitch should be about a quarter-inch long, and the thread should be snug enough that the fold closes completely but not so tight that it puckers the fabric. If you pull too hard, the fabric will bunch and the stitch will show on the outside.

When you've stitched about 18 inches (or when the thread gets short), tie a small knot inside the fold, trim the thread, and re-thread your needle. Continue around the entire hem until you reach your starting point. Tie off the final knot inside the fold and trim the thread.

Press the hem to set the stitches permanently

Once you've finished stitching, lay the garment flat and press the hem with an iron on low to medium heat. Use a pressing cloth (a thin cotton cloth or even a clean kitchen towel) between the iron and the fabric to protect delicate materials. Press from the inside of the garment first, then flip it over and press from the outside.

The heat sets the fold and flattens the stitches so they're less visible. Let the garment cool completely before you wear it—the fabric needs time to set the crease. If the hem still looks wavy or uneven after pressing, you can re-press it, but avoid pressing over the stitches repeatedly, as this can wear out the thread.

Common mistakes to avoid

The most common mistake is pulling the thread too tight, which causes the fabric to pucker and makes the stitch visible from the outside. Keep your tension loose enough that the fold closes gently. Another mistake is using thread that's too long—anything over 18 inches will tangle and knot as you work, wasting time and creating weak spots in the stitch.

Don't skip the double fold. A single fold leaves a raw, frayed edge that will unravel in the wash. Always fold twice (or once on very thick fabric) to hide the raw edge completely. Finally, don't rush the measuring step. An uneven hem is the most noticeable flaw, so take time to mark the line carefully and check it from multiple angles before you start stitching.

Frequently Asked Questions

How long does hand hemming actually take?

A straightforward pant leg takes 20 to 30 minutes if you're working at a comfortable pace. A full skirt or dress hem can take 45 minutes to an hour because there's more fabric to stitch. Speed comes with practice—your first hem will take longer than your fifth.

Can I use any thread, or does it have to be special sewing thread?

Use regular sewing thread, not embroidery thread or craft thread. Sewing thread is strong enough to hold up to washing and wearing. Match the color to your fabric as closely as possible for the most invisible result.

What if my hem comes undone after I wash the garment?

This usually means the thread wasn't knotted securely at the start and end, or the stitches were too loose. When you re-stitch it, tie a larger knot and keep the thread tension snug (but not tight). You can also add a small knot every 6 inches along the hem for extra security on garments that get heavy wear.

Is hand hemming strong enough for jeans or heavy pants?

Yes, but it takes longer because the fabric is thick. Use a shorter needle if you have one, and push harder to get through all the layers. Some people use a thimble on their pushing finger to protect it. Hand stitches are just as strong as machine stitches if they're done correctly.

Can I hand hem a curved hem, like on a circle skirt?

You can, but it's difficult because the curve causes the fabric to bunch. The stitches will be visible and the hem may look wavy. For curved hems, a sewing machine is much faster and gives a better result. Stick to hand hemming for straight edges.
