The basic repair: a straightforward running stitch closes small holes

A hole in jeans is one of the easiest repairs to do by hand. You thread a needle, tie a knot, and sew back and forth across the hole in a straight line. The stitches pull the fabric edges together and seal the gap. For a hole smaller than a quarter-inch across, a running stitch—the most basic hand-sewing technique—will hold for months of wearing and washing.

The repair works because denim is thick and sturdy. Your stitches don't need to be perfect or invisible. They just need to be tight enough that the hole doesn't unravel further. Most holes in jeans happen on the inner thigh or at the crotch seam, where fabric rubs against itself. A few rows of stitching will reinforce that spot and stop the damage from spreading.

Key Takeaways

  • A running stitch—pushing the needle in and out in a straight line—closes small holes and takes five to ten minutes.
  • Use thread that matches your jeans color, a needle small enough to fit through denim, and tie a knot at the end before you start.
  • Sew back and forth across the hole at least twice to make the repair strong enough to survive washing.
  • For holes larger than half an inch or in high-stress areas like the crotch seam, a patch sewn underneath the hole will last longer than stitching alone.

What you need: thread, needle, and scissors

Gather a needle, thread, and scissors. The needle should be small enough to push through denim without bending—a size 7 or 8 needle works well for most jeans. The thread should match your jeans as closely as possible. If your jeans are dark blue, use dark blue thread. If you cannot find an exact match, choose a shade slightly darker rather than lighter, because darker thread is less noticeable.

You do not need special jeans thread or heavy-duty thread. Regular all-purpose sewing thread is strong enough for a small hole. If you are repairing a large hole or reinforcing a seam, you can use buttonhole thread or upholstery thread, which is thicker and more visible but holds better under stress. For most repairs, though, standard thread works fine.

You will also need scissors to cut the thread. A small pair of sewing scissors is ideal, but any sharp scissors will do. Do not use kitchen scissors if you can avoid it—they dull quickly on thread.

How to thread the needle and tie a knot

Cut a length of thread about 18 inches long. Wet the end slightly between your lips or with a damp finger—this makes the thread stiffer and easier to push through the needle's eye. Push the thread through the needle. If it keeps fraying, trim the end with scissors and try again.

Once the thread is through, pull it so one end is much longer than the other. You want about 2 inches on the short end and 16 inches on the long end. Tie a knot at the short end by looping the thread around your finger, pulling it tight, and sliding the loop off your finger. The knot should be small and firm. This knot will catch on the fabric and keep your thread from pulling all the way through when you start sewing.

Sewing the hole: the running stitch

Position the hole so you can see it clearly. Push the needle through the fabric about a quarter-inch to one side of the hole, from the inside of the pant leg outward. The knot will catch on the inside and stop the thread. Pull the thread until it is snug but not tight enough to pucker the fabric.

Now push the needle back through the fabric on the other side of the hole, about a quarter-inch away. You have made one stitch. Pull the thread snug again. Repeat this motion—in one side, out the other—moving forward along the hole. Each stitch should be about a quarter-inch long. You are creating a line of stitches that crosses the hole and holds the edges together.

Once you reach the end of the hole, turn around and sew back over the same line. This second pass reinforces the repair and fills any gaps. For a small hole, two passes are usually enough. For a larger hole or one in a high-stress area, sew a third pass parallel to the first two, about a quarter-inch to the side.

Finishing the repair and tying off

When you have finished sewing, push the needle to the inside of the pant leg and make a small stitch in place—push the needle through the fabric and back out in almost the same spot, creating a loop. Pull the thread snug. Repeat this tiny stitch two or three times in the same spot. This creates a knot on the inside of the fabric that will not come undone.

Trim the thread close to the fabric with scissors. The repair is complete. Turn the pant leg inside out and inspect your work. You should see a line of stitches crossing the hole, with a small knot at each end on the inside of the fabric.

When to use a patch instead of stitching alone

If the hole is larger than half an inch across, or if it is in a seam or a high-stress area like the inner thigh or crotch, a patch will last longer than stitches alone. A patch is a small piece of fabric sewn underneath the hole to reinforce it. You can buy iron-on patches at a fabric store, or you can cut a patch from scrap denim and sew it by hand.

To sew a patch, cut a square of fabric about an inch larger than the hole on all sides. Position it on the inside of the pant leg, behind the hole. Sew around the edges of the patch using a running stitch, staying about a quarter-inch from the edge. Then sew across the hole itself using the same running stitch, as you would without a patch. The patch spreads the stress of the hole across a larger area, so the repair holds up better to washing and wearing.

Washing and caring for the repair

Your repair is ready to wear when ready. You can wash the jeans the next time you do laundry. Wash them inside out to protect the stitches, and use cold water if possible. The stitches will not come loose in the washing machine—hand-sewn thread on denim is durable enough for regular wear.

Over time, the repair may loosen slightly or the hole may grow if the fabric around it continues to wear. If that happens, you can re-sew the same spot or add a patch. Most hand-sewn repairs on jeans last for several months of regular wearing before they need reinforcement.

Frequently Asked Questions

Can I sew a hole in jeans while wearing them?

No. You need to remove the jeans and lay them flat on a table or hold them in your lap with the hole visible and accessible. Sewing while wearing them risks sewing the fabric to your leg or missing the hole entirely.

What if my thread keeps breaking?

Your needle may be too small, or the thread may be catching on rough edges of the hole. Try a slightly larger needle, or use a thicker thread like buttonhole thread. If the fabric is frayed, trim the loose threads around the hole with scissors before you start sewing.

Do I have to match the thread color exactly?

No, but a close match looks better. If you cannot find matching thread, choose a shade darker than your jeans rather than lighter. Dark thread is less noticeable than light thread on dark fabric.

How long does a hand-sewn repair last?

A repair on a small hole typically lasts several months of regular wearing and washing. Holes in high-stress areas like the crotch seam may need reinforcement sooner. Adding a patch underneath extends the life of the repair significantly.

Can I use a sewing machine instead?

Yes, a sewing machine will create a stronger, faster repair. However, hand sewing works fine for small holes and requires no equipment beyond a needle and thread.
