The fastest way depends on hole size and where it is

A small hole in the armpit or side seam can be closed in five minutes with a needle and thread. A hole in the middle of the chest or back needs a patch or a wider stitch to hold. The method you choose depends on whether you want the repair invisible, whether the shirt matters enough to spend time on it, and whether the fabric around the hole is still strong enough to hold stitches.

All four methods below work on cotton, cotton blends, and most knits. Avoid these methods on very thin or stretchy fabrics like silk or spandex — those need a professional or a sewing machine. You will need a needle, thread that matches the shirt color, and scissors. A patch method also needs fabric scraps or iron-on patch material from a fabric store.

Key Takeaways

  • A hole smaller than a dime in a seam or armpit closes fastest with a ladder stitch, which is nearly invisible and takes about five minutes by hand.
  • A hole in the middle of fabric needs either a patch sewn on top or a whip stitch around the edges, depending on whether you want the repair to show.
  • Thread color matters — use a shade that matches the shirt, not white thread on a dark shirt, or the repair will be obvious from across the room.
  • A hole larger than a quarter will not hold with stitching alone and needs a fabric patch behind it or an iron-on patch on top.

The ladder stitch for seams and small holes

Use this method on holes in the armpit, along a side seam, or anywhere the hole runs along a seam line. The ladder stitch closes the hole from the inside and leaves almost no visible thread on the outside.

Thread your needle and tie a knot at the end. Push the needle through the fold of one side of the seam, about a quarter inch away from the hole. Slide the needle inside the fold of the seam for about half an inch, then push it back out. Cross over to the opposite side of the seam and repeat — push in a quarter inch away from the hole, slide inside the fold for half an inch, push back out. Keep going back and forth, staying inside the seam fold. Every third or fourth stitch, pull the thread snug. The two sides of the seam will draw together and close the hole. After you pass the hole by about half an inch, tie off the thread inside the seam fold and trim it.

This stitch works because you are pulling the fabric closed from inside the seam, not trying to bridge the hole with thread. It is the strongest repair for small holes and nearly invisible from the outside.

The whip stitch for holes in the middle of fabric

A hole in the chest, back, or sleeve that is not on a seam needs a whip stitch. This stitch closes the edges of the hole by catching the fabric on both sides. It is visible but strong, and it works on holes up to about a quarter inch across.

Thread your needle and tie a knot. Push the needle through the fabric about an eighth of an inch to the left of the hole, coming out right at the edge of the hole. Now push the needle straight across the hole into the fabric on the opposite side, also right at the edge. Bring the needle back out about an eighth of an inch further along. You are making small stitches that catch the very edge of the hole on each pass. Keep going around the hole, making stitches about an eighth of an inch apart. Pull gently as you go — the edges of the hole will curl inward and close. After you go all the way around, tie off the thread on the underside and trim it.

The whip stitch leaves a visible line of thread around the hole, but it is much stronger than trying to bridge the hole. On a dark shirt, use dark thread. On a light shirt, match the shirt color as closely as you can.

The patch method for larger holes

Any hole larger than a quarter inch needs a patch. A patch can go on top of the hole (visible but durable) or behind it (hidden but requiring more work). Fabric stores sell iron-on patches that stick with heat, or you can sew a patch by hand.

For a hand-sewn patch, cut a piece of fabric at least an inch larger than the hole on all sides. Cotton fabric from an old shirt works fine. Place the patch behind the hole on the inside of the shirt. Thread your needle and tie a knot. Starting at one corner of the patch, push the needle through both the patch and the shirt fabric. Make small stitches around the entire edge of the patch, about a quarter inch apart. Go all the way around and tie off the thread. The patch will be hidden on the inside and will hold the hole closed from behind.

For an iron-on patch, follow the instructions on the package — usually you place the patch over the hole on the outside, cover it with a thin cloth, and press with a hot iron for 10 to 15 seconds. Iron-on patches are faster but less durable over many washes. A sewn patch lasts longer.

Choosing thread color and needle size

Thread color is the difference between a repair that blends in and one that stands out. Buy thread that matches the shirt as closely as you can. If the shirt is navy, use navy thread, not black or white. If the shirt is a print, use the dominant color. Most fabric stores have thread in dozens of colors for a dollar or two per spool.

Needle size matters less for hand sewing than it does for machines, but a size 7 or 8 needle works for most cotton and cotton-blend shirts. The needle should slide through the fabric without tearing it. If the needle is too thick, it will leave visible holes. If it is too thin, it will bend or break. A basic sewing needle pack from any drugstore has several sizes and costs less than a dollar.

When to use a sewing machine instead

A sewing machine closes holes faster and stronger than hand sewing, but it requires practice and the right settings. If you own a machine and know how to use it, a zigzag stitch over the hole or a patch sewn with a straight stitch will outlast any hand repair.

If you do not own a machine or have never used one, hand sewing is faster to learn and works well for most holes. A machine is worth learning if you repair clothes regularly, but for a single hole in a single shirt, hand sewing is the practical choice.

Frequently Asked Questions

How do I keep a hole from getting bigger after I sew it?

Wash the shirt gently in cold water and hang it to dry instead of using the dryer. The dryer's heat and tumbling can stress the repair. Avoid wearing the shirt during activities that stretch that area — if the hole was in the armpit, avoid overhead movements for a few days after sewing.

What if the fabric around the hole is torn and weak?

If the edges of the hole are frayed or the fabric is thin, stitching alone will not hold. Use a patch behind the hole to distribute the stress across a larger area of fabric. A patch is the only repair that works when the fabric itself is damaged, not just the hole.

Can I sew a hole in a stretchy shirt like a t-shirt with spandex?

Hand sewing works but the repair may not stretch with the fabric and can break after a few wears. If the shirt is mostly spandex or very stretchy, a sewing machine with a stretch stitch setting is better. For a basic cotton t-shirt, hand sewing holds fine.

How long does a hand-sewn repair last?

A ladder stitch on a seam can last years if the seam itself is strong. A whip stitch on fabric in the middle of the shirt usually lasts 20 to 50 washes before the thread wears through. A sewn patch lasts longer — often 100 washes or more — because the patch distributes stress across more fabric.

Should I wash the shirt before or after sewing the hole?

Wash it before. A clean shirt is easier to work with, and you can see the hole clearly without dirt or stains in the way. Let it dry completely before you start sewing so the fabric is not damp and slippery.
