How to Hem and Tailor Your Own Clothes

A needle, thread, and ten minutes can transform an ill-fitting garment into something that actually works. Here's how to do basic alterations at home without fear.

Most of us own at least one piece that fits almost perfectly—except the hem is too long, the sleeves pool at your wrists, or the waistband gapes. Before you consign it to the donation pile or pay $40 for professional tailoring, consider this: basic alterations are genuinely learnable. You don't need a sewing machine, steady hands, or years of experience. A simple running stitch and a bit of patience will do.

The goal here isn't invisible couture seams. It's functional, honest alterations that make your existing clothes actually wearable. Think of it as extending the life of pieces you already love while building a skill that pays for itself after three or four repairs.

A simple running stitch and a bit of patience will do more than you'd expect.

What you'll need.

  • 01Hand-sewing needle (size 7–9 for most fabrics)
  • 02All-purpose thread in a matching color
  • 03Small sharp scissors
  • 04Safety pins or tailor's pins
  • 05Measuring tape
  • 06Iron (optional but helpful)

Step one · 2 minutes

Measure twice, cut never

Put on the garment and have someone pin the hem to the correct length, or use a mirror and safety pins to mark where it should sit. For pants, aim for a slight break at the shoe—not dragging, not flooding. For skirts, mark the desired length while wearing the shoes you'll actually pair with it. Try it on again to confirm the pins are level all around. This step prevents costly mistakes.

If you're hemming alone, wear the shoes you'll wear with the garment and stand on a stable chair to check the length in a full-length mirror.

Step two · 1 minute

Prepare your needle and thread

Cut about 18 inches of thread and thread your needle. Tie a small knot at one end. Match your thread color as closely as possible to the garment—an exact match isn't necessary, but a thread that's too light or dark will be visible. For a stronger hold, use doubled thread (thread the needle with two strands instead of one).

Keep thread shorter than 18 inches to prevent tangling and fraying as you work.

Step three · 3 minutes

Fold and secure the hem

Fold the garment's edge up to your pin line and press it flat with your fingers or a quick iron pass. This crease is your guide. Starting from the inside of the garment, push your needle through the folded hem, bringing it out just below the fold. Then make a tiny stitch (about 1/8 inch) into the main fabric directly above, and bring the needle back through the fold. Repeat this pattern along the entire hem, keeping stitches small and even.

Work from left to right if you're right-handed. Keep tension loose—too tight and the fabric will pucker.

Step four · 1 minute

Finish the thread

When you reach the end of the hem, make a small stitch and pull the needle through, leaving a small loop. Pass the needle through that loop twice to create a knot, then trim the excess thread close to the fabric. The knot should sit inside the fold of the hem, hidden from view.

If your thread runs out before the hem is complete, tie it off and start a new length, overlapping your stitches by about half an inch.

Step five · 2 minutes

Try it on and assess

Remove the pins and try on the garment. Walk around, sit down, bend—test it the way you actually wear it. Check that the hem sits evenly and the stitches hold. If you notice puckering or loose spots, you can add a few reinforcement stitches in those areas. For sleeve hems, this step is especially important since sleeves move a lot.

If the hem feels stiff after sewing, a gentle wash will relax the fabric and make it feel more natural.

Know when to call a professional

Hand-hemming works beautifully for straight hems on pants, skirts, and sleeves. It's less ideal for curved hems, delicate fabrics prone to fraying, or garments with complex construction. If you're working with silk charmeuse, a curved neckline, or a piece you genuinely love and can't replace, professional tailoring is worth the investment. This skill is about extending the life of everyday pieces, not replacing expert work.

Save this method for cotton, linen, wool, and sturdy blends. Delicate fabrics benefit from a professional touch.

How to know it works.

A successful hem is invisible from the outside, holds through multiple wears and washes, and feels natural against your leg or arm. The stitches should be small, even, and snug but not tight. If the hem puckers, pulls, or comes loose after one wear, the tension was too tight or the stitches too far apart—both fixable on your next attempt.

Questions at the mirror.

My thread keeps tangling and knotting as I sew.

You're likely using too much thread at once. Cut it to 12–18 inches maximum. Also, always thread the needle the same direction you cut it—this reduces tangling. If it still happens, run the thread through a small piece of beeswax or candle wax to smooth it.

The hem looks uneven on one side.

This usually means the fold wasn't crisp or level when you started. For your next hem, use an iron to press the fold firmly before sewing. If it's already done, you can add a few reinforcement stitches to the loose side.

Can I use this method on stretchy fabrics like jersey or spandex blends?

Hand-hemming works but requires patience. Use a ballpoint needle (designed for knits) and keep tension very loose. For frequent-wear pieces in stretchy fabrics, a sewing machine or professional tailor is more durable.

How long will a hand-sewn hem last?

With normal wear and care, a well-executed hand hem lasts through dozens of washes and wears. If a stitch breaks, you can simply tie it off and reinforce that spot. The hem isn't permanent, but it's meant to be—you can always adjust it later.
