The basic stitch for closing a hole

The fastest way to close a hole is a ladder stitch, also called a slip stitch. It pulls the fabric edges together from the inside so the seam is nearly invisible on the outside. You thread a needle, anchor it inside the fold of one edge, then run it back and forth between the two fabric edges in a zigzag pattern. The thread stays hidden inside the fold as you work, and when you pull it tight at the end, the hole closes.

Start by threading a needle with thread that matches your fabric. Knot the end. Push the needle through the fold of fabric on one side of the hole — not through the top layer, but into the crease where two layers meet. Bring it out about a quarter-inch away. This hides your knot inside the fold.

Now push the needle straight across into the fold on the opposite side of the hole, at the same height where you came out. Run it along inside that fold for a quarter-inch and come back out. Go back to the first side and repeat. After every three or four stitches, pull the thread gently to draw the edges together. The hole will close as you work.

Key Takeaways

  • A ladder stitch hides the thread inside the fabric fold, making the repair invisible from the outside.
  • Match your thread color to the fabric so any visible stitches blend in.
  • Pull the thread gently every few stitches to close the hole gradually rather than all at once.
  • For small holes under half an inch, a ladder stitch alone is enough; larger holes need a patch underneath first.
  • Backstitch at the end and tie off inside the fold to keep the repair from coming loose.

When to use a patch underneath

A ladder stitch works well for small tears and holes, but anything larger than half an inch will pull apart again under wear. For bigger damage, cut a patch from matching fabric — or use iron-on patch material if you want to skip sewing it down first.

Position the patch on the inside of the garment, centered over the hole. If you are using iron-on material, follow the package directions for heat and pressure. If you are sewing it, use a straightforward running stitch around all four edges, about a quarter-inch from the edge of the patch. Then use the ladder stitch to close the hole itself on the outside. The patch underneath keeps the repair from tearing open again.

Fixing a seam that has split

When a seam splits — usually at a stress point like an armpit or crotch — the repair is different from patching a hole in the middle of fabric. You are re-sewing the original seam line, not creating a new one.

Turn the garment inside out. Line up the two edges that have separated and pin them together so they sit exactly as they did before the split. Thread a needle with thread that matches the garment. Use a backstitch, which is stronger than a running stitch: push the needle through both layers, come back out a quarter-inch ahead, then push it back to where you started and come out another quarter-inch ahead. This creates a solid line of overlapping stitches.

Sew the entire length of the split seam. When you reach the end, backstitch three or four times in the same spot to lock the thread, then tie it off on the inside. If the seam is under heavy stress, sew it twice — once along the original seam line and once a quarter-inch to the side.

Choosing the right needle and thread

The needle size and thread weight matter. A needle that is too large will leave visible holes in delicate fabric; one that is too small will bend or break. For most clothing repairs, a size 70/10 or 80/12 needle works on cotton, linen, and blends. Use a size 60/8 for very fine fabrics like silk or thin knits, and a size 90/14 for heavier materials like denim or canvas.

Thread comes in different weights. All-purpose thread is fine for most repairs. Buttonhole thread is thicker and stronger if you are repairing a seam under stress. Match the thread color as closely as you can — hold it up to the fabric in natural light, not under a lamp. If you cannot find an exact match, choose one shade darker rather than lighter; it will be less noticeable.

How to tie off and find the end

A repair that comes loose defeats the purpose. After your last stitch, bring the needle to the inside of the garment. Make a small loop with the thread and push the needle through it, pulling tight. Repeat this knot two more times in the same spot. This creates a knot that will not slip.

For extra security on a seam repair, backstitch three or four times in the same spot before you tie off. This locks the thread in place so even if the knot loosens, the stitches will hold. Trim the thread close to the knot.

Repairing holes in knit fabric

Knit fabric — like t-shirt material or sweaters — tears differently than woven fabric and needs a different approach. A straightforward ladder stitch can work, but knits are stretchy and the hole may pucker. A better method is to use a patch on the inside and then close the hole with a ladder stitch, just as you would for a larger woven hole.

Alternatively, if the hole is very small and in a place that does not get much stress, you can use a tiny whip stitch: bring the needle up through one edge of the hole, then down through the other edge right next to it, and repeat all the way around. This pulls the edges together without a patch. Work slowly and keep the stitches small so the fabric does not pucker.

Common mistakes that weaken a repair

Pulling the thread too tight too soon will pucker the fabric and make the repair visible. Pull gently and evenly as you work, not all at the end. Skipping the knot or tying off poorly means the repair will come loose the first time the garment is washed or worn hard. Always tie off with at least two knots, and make them on the inside where they will not catch.

Using thread that does not match the fabric color makes even a well-sewn repair obvious. Choosing a needle that is too large leaves holes that weaken the fabric further. And rushing through the stitches — making them too long or uneven — means the repair will not hold under stress. Take your time, keep stitches small and even, and the repair will last.

Frequently Asked Questions

Can I sew a hole closed without a patch?

Yes, if the hole is small — under half an inch — a ladder stitch alone will hold. Anything larger needs a patch underneath to distribute the stress and keep the repair from tearing open again when the garment is worn or washed.

What is the difference between a ladder stitch and a backstitch?

A ladder stitch hides inside the fabric fold and is nearly invisible from the outside, making it best for closing holes. A backstitch is visible and very strong, making it the right choice for re-sewing seams that have split or for attaching patches.

How do I keep my repair from showing?

Match your thread color to the fabric as closely as possible, work with small even stitches, and use a ladder stitch whenever you can — it hides the thread inside the fold. Pull the thread gently as you work so the fabric does not pucker. A repair that is sewn neatly with matching thread will be far less noticeable than one rushed with contrasting thread.

Will a repair hold after washing?

Yes, if you tie off the thread properly with at least two knots and use a patch for any hole larger than half an inch. Wash the garment in cold water and hang it to dry rather than using the dryer, which puts more stress on seams and repairs. A well-sewn repair will last through many washes.

What should I do if I break the thread while sewing?

Tie off the thread you have already sewn with a knot on the inside. Thread a new needle with fresh thread and start again a quarter-inch before where you stopped, overlapping your previous stitches slightly. This overlap keeps the repair from having a weak spot where the old thread ended.
