The Basic Stitch for a Straight Tear

A ladder stitch (also called a slip stitch) is the fastest way to close a rip so the repair is nearly invisible. You thread a needle, anchor it inside the fold of fabric on one side of the tear, then run the needle back and forth between the two folded edges, catching just a few threads each time. The thread stays hidden inside the fold, and when you pull it tight at the end, the two sides of the fabric pull together and the seam disappears.

This works best on tears that run along a seam or on fabric that has a natural fold you can use—like the side seam of a shirt or the edge of a pillowcase. If your tear is in the middle of flat fabric with no fold, you will need a different approach (see the section on patching below).

The whole repair takes 5 to 10 minutes once you have threaded your needle. You will need thread that matches your fabric color, a needle small enough to pass through the weave without leaving visible holes, and scissors.

Key Takeaways

  • A ladder stitch works by running your needle through the fold of fabric on each side of the tear, staying hidden inside the fold so the repair is invisible from the outside.
  • Start by anchoring your thread inside the fold, then make small stitches (about 1/8 inch) that alternate between the left and right sides of the tear.
  • Pull the thread tight every few stitches to close the gap, and finish by knotting the thread inside the fold so the knot stays hidden.
  • For tears in the middle of flat fabric or large rips, a patch sewn on the inside of the garment is stronger and more reliable than a ladder stitch alone.

Threading Your Needle and Starting the Repair

Cut a length of thread about 18 inches long—long enough to complete most small repairs without running out, but short enough that it will not tangle as you work. If your thread is longer than that, it will fray and knot. Thread it through the eye of your needle and pull it so one end is about 4 inches longer than the other. Tie a knot at the end of the longer piece.

Locate the fold of fabric closest to your tear. If you are repairing a seam, this is the seam itself. If you are repairing a tear on a flat surface, you may need to fold the fabric slightly to create a fold you can work with. Insert your needle into the fold about 1/2 inch away from where the tear begins, and push it through the fold so the knot stays on the outside and the thread emerges inside the fold, right at the start of the tear. This anchors your thread so it will not pull out as you work.

Making the Ladder Stitch: The Step-by-Step Motion

Once your needle is anchored inside the fold, bring it out through the fold on the opposite side of the tear, about 1/8 inch forward along the seam. You have now made your first stitch. The thread is still hidden inside the fold.

Now insert the needle back into the fold on the first side, directly across from where you just came out, and push it forward about 1/8 inch inside the fold. Bring the needle back out through the fold. You have now made a second stitch on the opposite side. The pattern is: out on the left, in on the right, out on the right, in on the left, and repeat.

Keep the stitches small and even—about 1/8 inch apart. Do not pull the thread tight yet. After every 4 or 5 stitches, stop and gently pull the thread so the two sides of the tear come together. You will see the fabric close up as you pull. Then continue stitching. This gradual tightening prevents the thread from breaking and keeps the repair even.

Finishing the Repair and Hiding the Knot

Once you have stitched past the end of the tear by about 1/2 inch, stop and pull the thread one final time so the tear is completely closed. The two edges of fabric should be touching with no gap. If there is still a small gap, make a few more stitches and pull again.

To finish, bring your needle out through the fold one last time, but do not pull it all the way through. Instead, loop the thread around the needle and push the needle back through the loop to create a knot. Pull the thread tight so the knot cinches, then push the needle back into the fold and out again about 1/2 inch away. Pull the thread so it breaks at the knot, leaving the knot hidden inside the fold. Trim any loose thread.

When to Use a Patch Instead of a Ladder Stitch

A ladder stitch works only if you have a fold of fabric to hide the thread in. If your tear is in the middle of a flat piece of fabric—like a hole in the knee of jeans or a rip across the back of a shirt—you cannot use a ladder stitch. Instead, sew a patch on the inside of the garment.

Cut a patch from matching fabric (or contrasting fabric if you want it to show) that is at least 1 inch larger than the tear on all sides. Pin it over the tear on the inside of the garment so the tear is centered on the patch. Thread your needle and sew around the edge of the patch using a straightforward running stitch (in and out, in and out, about 1/8 inch apart). Make sure your stitches go through both the patch and the garment fabric. Once you have sewn all the way around, tie off the thread inside the fold of the patch edge.

A patch is stronger than a ladder stitch for large tears or areas that get a lot of stress, like the crotch of pants or the elbow of a jacket. The downside is that it is visible from the inside, though it is hidden from the outside.

Common Mistakes and How to Avoid Them

The most common mistake is pulling the thread too tight too soon. If you yank the thread after every stitch, it will bunch the fabric and create puckers instead of a smooth seam. Pull gently and only every few stitches. The fabric should close gradually, not all at once.

Another mistake is making stitches that are too large. If your stitches are more than 1/4 inch apart, the thread will not hold the tear closed and it will reopen the next time you wash or wear the garment. Aim for 1/8 inch stitches, and keep them even so the repair looks neat.

Do not use thread that is too thick or too thin. Thread that is too thick will leave visible holes in delicate fabric and will be hard to push through. Thread that is too thin will break under stress. All-purpose sewing thread in a weight that matches your fabric is the safest choice.

Finally, do not skip the anchor stitch at the beginning. If you just tie a knot at the end of your thread and start stitching, the knot will pull through the fold and your repair will fall apart. Always insert the needle into the fold first, so the knot stays on the outside and the thread is anchored inside.

How to Reinforce a Repair That Gets Heavy Use

If you have repaired a tear in a high-stress area—like the seam of a bag that you carry every day, or the crotch of work pants—you can make the repair stronger by sewing over it a second time. Once your first ladder stitch is complete and the thread is tied off, thread your needle again with fresh thread and sew the same seam a second time, placing your stitches slightly offset from the first row so you are not retracing the exact same path.

This double-stitched seam will hold much longer than a single row of stitches. It takes only a few extra minutes and can add months or years to the life of the garment. You can also reinforce a patch by sewing around the edge a second time, or by sewing an X pattern across the middle of the patch for extra strength.

Frequently Asked Questions

What kind of thread should I use?

All-purpose polyester or cotton thread in a color that matches your fabric is the standard choice. If you cannot find an exact match, choose a color slightly darker than your fabric—it will be less visible than a lighter shade. Avoid embroidery thread or very thick thread, as these will leave visible holes and are hard to work with on small repairs.

Can I use a ladder stitch on stretchy fabric like a t-shirt?

A ladder stitch works on knit fabric, but the repair may not stretch as much as the surrounding fabric. For a t-shirt or other stretchy garment, use a patch on the inside instead, or sew the ladder stitch and then sew a small patch over it for reinforcement. This keeps the repair flexible so it does not break when you move.

How do I fix a tear that is not straight?

If the tear is jagged or curved, use a ladder stitch if there is a fold to work with, but make your stitches smaller (about 1/16 inch) so you can follow the curve of the tear more closely. If the tear is in flat fabric, a patch is your best option because it will cover the entire damaged area and prevent the tear from spreading.

What if my thread keeps breaking?

Your thread is probably too long, or you are pulling it too hard. Cut a fresh length of thread no longer than 18 inches, and pull gently when closing the tear. If the thread still breaks, you may be using thread that is too thin for your fabric—switch to a thicker all-purpose thread.

How long will a hand-sewn repair last?

A well-sewn ladder stitch on a seam can last for years if the garment is not under heavy stress. A patch will last longer because it distributes the stress over a larger area. Washing and drying by machine will not damage a hand-sewn repair, but repeated stress on the same spot—like the knee of pants you wear every day—will eventually cause the thread to wear through. Reinforce high-stress repairs with a second row of stitches or a patch.
