The Basic Stitch for Small Holes
The simplest way to close a small hole is with a ladder stitch (also called a slip stitch), which pulls the fabric edges together from the inside so the seam is nearly invisible. You thread a needle, knot the end, and use a series of small stitches that run inside the fold of the fabric rather than across the hole itself. The hole closes as you pull the thread tight.
Start by threading a needle with thread that matches your fabric color as closely as possible. Tie a knot at the end of the thread. Push the needle through the fold of fabric on one side of the hole, about a quarter-inch away from the edge. Bring it out through the fold, then cross directly to the opposite side of the hole and push the needle back into the fold at the same distance from the edge. Run the needle inside the fold for about a quarter-inch, then come back out. Repeat this back-and-forth motion along the entire length of the hole.
Every few stitches, gently pull the thread to draw the fabric edges together. You will see the hole begin to close. Once you reach the end, tie off the thread on the inside by making a small loop and pulling the needle through it twice. Trim the excess thread.
Key Takeaways
- The ladder stitch works best for holes smaller than half an inch and leaves almost no visible seam on the outside of the fabric.
- Thread color matters—a mismatch will show even if your stitches are perfect, so spend a moment finding the closest match at the store.
- Pulling the thread too hard too fast can pucker the fabric, so tighten gradually as you work your way along the hole.
- Larger holes or tears in knit fabrics may need a patch or a different stitch, because the ladder stitch alone cannot hold fabric that has separated too far.
- Practice on scrap fabric first so you develop a feel for how much tension the thread needs before you repair something you wear regularly.
Repairing Larger Tears with a Patch
When a hole is larger than half an inch, or when the fabric edges have frayed or separated too much for a ladder stitch to hold, a patch is more durable. A patch is a piece of fabric sewn over the hole on the inside of the garment, which reinforces the weak area and prevents the tear from spreading.
Cut a square or rectangle of fabric at least an inch larger than the hole on all sides. Cotton fabric, denim, or canvas work well for patches because they do not fray as easily as lighter materials. If the hole is in a visible spot and you want the patch to be hidden, use fabric that matches the garment. If you are repairing work clothes or do not mind a visible patch, you can use contrasting fabric for a deliberate look.
Turn the garment inside out. Center the patch over the hole and pin it in place. Thread your needle and knot the end. Sew around the entire perimeter of the patch using a straightforward running stitch—push the needle through both the patch and the garment fabric, pull it through, and repeat in a straight line about a quarter-inch from the edge. Space your stitches about a quarter-inch apart. Once you have sewn all four sides, tie off the thread on the inside.
For extra strength, sew a second line of stitches about a quarter-inch inside the first line, creating a rectangle within the patch. This double-stitched border holds much better than a single line, especially on garments that get heavy wear.
Closing Seam Splits and Underarm Tears
Seams split when the thread holding two pieces of fabric together breaks, usually from stress or repeated movement. An underarm tear is a common example—the fabric itself is usually fine, but the seam has given way. This repair is different from closing a hole because you are re-stitching along an existing seam line rather than creating a new one.
Turn the garment inside out so you can see the seam clearly. Look at the existing stitches on either side of the split to understand the stitch pattern and spacing. Thread a needle with thread that matches the garment, knot the end, and start stitching at one end of the split, following the original seam line as closely as possible. Use a straightforward running stitch, spacing your stitches about the same distance apart as the original stitches.
Sew past the end of the split by about half an inch to anchor the repair. Tie off the thread on the inside. If the seam has split over a long distance or if the fabric around the seam is worn thin, sew a second line of stitches parallel to the first, about a quarter-inch away. This reinforces the repair and prevents the seam from splitting again in the same spot.
Mending Holes in Knit Fabrics Like T-Shirts and Sweaters
Knit fabrics—the stretchy material in t-shirts, sweaters, and leggings—tear differently than woven fabrics. A hole in a knit can unravel quickly because the loops of yarn are not locked together the way woven threads are. The ladder stitch still works, but you need to be more careful about tension and you may need to reinforce the repair with a patch underneath.
For a small hole in a knit, use the ladder stitch as described above, but pull the thread more gently and more gradually. Knit fabric is more delicate than woven cotton, and too much tension will distort the surrounding stitches and create a puckered area larger than the original hole.
For a larger hole or a tear in a knit garment, use a patch on the inside combined with the ladder stitch on the outside. Cut a patch from knit fabric if possible—a t-shirt scrap works well—and sew it to the inside of the garment using a running stitch around all four edges. Then, from the outside, use the ladder stitch to close the hole itself. The patch prevents the hole from spreading, and the ladder stitch makes the repair less visible from the front.
Choosing the Right Thread and Needle
Thread color is the most important choice you will make. Even perfect stitches will show if the thread does not match the fabric. Bring the garment to a fabric or craft store and hold thread samples against it in natural light. A thread that looks close indoors may look obviously wrong in daylight. If you cannot find an exact match, choose a shade slightly darker rather than lighter—dark thread is less noticeable than light thread on most fabrics.
Needle size matters too. A needle that is too large will leave visible holes in delicate fabric, and a needle that is too small will be hard to push through thicker materials and may bend or break. For most clothing repairs, a size 7 or 8 needle works well. If you are sewing heavy denim or canvas, use a size 9 or 10. For delicate fabrics like silk or thin knits, use a size 5 or 6.
Use regular sewing thread, not embroidery thread or yarn. Sewing thread is strong and thin enough to disappear into the fabric, while embroidery thread is thick and meant to be visible. If you are patching heavy work clothes, you can use upholstery thread or buttonhole thread, which is thicker and stronger than regular sewing thread.
Common Mistakes and How to Avoid Them
The most common mistake is pulling the thread too tight too quickly. This puckers the fabric and makes the repair obvious. Instead, pull gently and gradually as you work, checking frequently to make sure the fabric lies flat. If you do pucker the fabric, you can sometimes fix it by gently stretching the area with your fingers while the garment is damp, then letting it air dry.
Another mistake is using thread that does not match the fabric color. This makes even a perfectly executed repair stand out. Spend the extra minute at the store to find the right shade. If the garment is a blend of colors—a striped shirt, for example—choose a thread that matches the dominant color or the color closest to the hole.
A third mistake is starting and ending the stitch without a proper knot. If you tie off carelessly, the thread can slip out and the repair will unravel. Always tie a knot at the end of the thread before you start, and always make a find knot on the inside of the garment when you finish. A good ending knot is made by creating a small loop with the thread, pulling the needle through it, and repeating once more before trimming the excess.
Finally, do not wait too long to repair a hole. A small hole that you ignore will grow larger as the fabric continues to fray and the surrounding threads weaken. A repair that takes five minutes now may take twenty minutes a month from now, or may become impossible if the hole spreads too far.
Frequently Asked Questions
What if I do not have thread that matches the fabric exactly?
Choose a thread one shade darker than the fabric rather than lighter. Dark thread blends better than light thread on most colors. If the garment is patterned, match the thread to the dominant color or the color closest to the hole itself.
Can I use a sewing machine instead of hand sewing?
Yes, for seam splits and patches. Set the machine to a straight stitch and sew along the seam line or around the patch edges. For small holes, a machine stitch is less delicate than a hand ladder stitch and may pucker the fabric more, so hand sewing is usually better. Always test on scrap fabric first.
How do I prevent holes from getting bigger?
Repair them as soon as you notice them. A small hole that sits for weeks will fray and spread. Also, wash and dry the garment gently—rough washing and high heat can weaken fabric around a hole and make it worse.
Is there a way to repair a hole without sewing?
Fabric glue and iron-on patches exist, but they do not hold as well as sewn repairs and often fail after a few washes. Sewing takes more time but lasts much longer. If you absolutely cannot sew, an iron-on patch is better than nothing, but expect it to need replacement within a few months.
What should I do if the hole is in a seam and the fabric is torn too?
Use both methods: re-stitch the seam line first, then add a patch on the inside if the fabric damage is significant. The seam repair closes the split, and the patch reinforces the weak area so it does not tear again in the same spot.
