The Basic Stitch for Small Holes

A small hole in a shirt — the kind from a snag or a worn seam — closes fastest with a ladder stitch, also called a slip stitch. This stitch is invisible from the outside because the thread runs inside the fold of fabric rather than across the hole itself. It works best on holes smaller than half an inch and on fabric that isn't heavily worn around the edges.

Thread a needle with thread that matches your shirt. Knot the end. Push the needle through the fold of fabric on one side of the hole, about a quarter inch away from the opening. Bring it out through the fold on the opposite side of the hole, also a quarter inch away. Now push the needle straight across through the hole itself, from one side to the other. Repeat this pattern — fold to fold, then across the hole — until the hole closes. Pull gently on the thread every few stitches so the fabric draws together. Tie off inside the fold when you're done.

Key Takeaways

  • The ladder stitch closes small holes invisibly by running thread through fabric folds rather than across the hole.
  • A patch sewn over the hole from the inside works for larger tears or holes in worn fabric.
  • Backstitch is the strongest choice for seams that have split open, because it creates a tight, durable line.
  • Knot your thread on the inside of the shirt so the knot doesn't show and won't catch on skin.
  • Use thread that matches your shirt color, or use clear thread if you don't have an exact match.

Patching a Larger Hole

If the hole is bigger than half an inch or the fabric around it is thin or frayed, a patch is stronger than stitching alone. Cut a piece of fabric — cotton or a blend that matches your shirt — into a square or rectangle about an inch larger than the hole on all sides. Round the corners so they don't fray or catch.

Place the patch on the inside of the shirt, centered over the hole. Pin it in place. Thread your needle and knot the end. Use a running stitch — pushing the needle in and out of the fabric in a straight line — around the edge of the patch, about a quarter inch from the edge. Keep your stitches small and even, roughly an eighth inch long. When you reach the starting point, tie off the thread on the inside.

If the hole is on a visible part of the shirt and you want it less noticeable, you can sew a decorative patch on the outside instead. A contrasting fabric patch can look intentional rather than like a repair.

Repairing a Split Seam

A seam that has split open needs a stronger stitch than a hole in solid fabric. Use a backstitch, which creates an overlapping line of thread that won't pull apart. This is the stitch to use on armholes, side seams, or anywhere the fabric is under tension.

Align the two edges of the split seam so they meet evenly. Pin them together if the fabric is slippery. Thread your needle and knot the end. Push the needle through both layers of fabric from underneath, about a quarter inch to the right of where you want to start. Bring it back out a quarter inch to the left of your starting point. Now push the needle back through the hole you just made, going forward another quarter inch. Repeat this pattern — backward a quarter inch, forward a quarter inch — along the entire seam. The thread will overlap itself and create a solid line. Tie off on the inside when you reach the end.

Choosing the Right Thread and Needle

Thread thickness matters. For lightweight fabrics like cotton or linen, use regular sewing thread. For heavier fabrics like denim or canvas, use upholstery thread or doubled regular thread — this means threading two strands through the needle at once. Thicker thread closes holes faster and holds longer under stress.

Match the thread color to your shirt if you can. If you don't have an exact match, clear thread works on most fabrics and is nearly invisible. Avoid white thread on dark shirts or dark thread on light shirts — the mismatch will show more than a slightly off color.

Use a needle size that matches your fabric. A size 70/10 or 80/12 needle works for most cotton shirts. Thicker fabrics need a larger needle — size 100/16 or 110/18. If your needle bends or breaks, you're using one that's too small for the fabric.

When to Use a Whip Stitch

A whip stitch is useful when you're closing a hole that has a finished edge — like a buttonhole that has torn, or a hem that has come undone. This stitch catches just the edge of the fabric rather than going through it completely, so it's less visible than a running stitch.

Bring the needle up through the fold of fabric on one side of the hole. Push it directly across into the fold on the opposite side, then slide the needle along inside the fold for about a quarter inch before bringing it back out. Repeat this pattern along the entire opening. The thread will sit mostly inside the fold and only catch the very edge of the fabric, making it nearly invisible from the outside.

Reinforcing Worn Fabric

If the area around the hole is thin or worn, stitching alone won't hold. The thread will pull through the weak fabric. In this case, use a patch on the inside and backstitch around its edge, then add a second line of stitching around the hole itself for extra strength.

Alternatively, you can use fusible interfacing — a fabric-like material with adhesive on one side that bonds to fabric when you iron it. Cut a piece slightly larger than the hole, place it on the inside of the shirt, and iron it according to the package directions. Once it's fused, sew around the hole with a ladder stitch or running stitch. The interfacing reinforces the weak fabric so your stitches won't pull through.

Finishing and Preventing Future Holes

After you've sewn the hole closed, trim any loose threads on the inside. If you used a patch, make sure all edges are sewn down and none are lifting. Check the repair by gently pulling on the fabric around the hole — it should feel solid, not loose.

To prevent holes from forming in the first place, wash your shirt inside out to reduce friction, avoid drying it on high heat (which weakens fibers), and repair small snags when ready before they become holes. Store shirts on hangers rather than in tight stacks, which can cause friction and wear.

Frequently Asked Questions

What if I don't have thread that matches my shirt?

Clear thread works on most fabrics and is nearly invisible. If you don't have clear thread, choose a color slightly darker than your shirt rather than lighter — dark thread shows less than light thread on most fabrics. Test on a hidden seam first to see how noticeable it is.

Can I sew a hole in a stretchy fabric like spandex or athletic wear?

Stretchy fabrics need a flexible stitch. Use a zigzag stitch if you have a sewing machine, or hand-sew with a ladder stitch and pull gently so the thread doesn't snap when the fabric stretches. A patch on the inside is often the most durable choice for athletic wear because the fabric is under constant tension.

How do I know if a hole is too big to sew?

If the hole is larger than an inch and the fabric around it is thin or frayed, sewing alone won't hold. Use a patch instead. If the hole is on a seam and the seam is completely separated for more than two inches, you may need to take the shirt to a tailor — repairing long seams by hand is time-consuming and the repair may not be as strong as a machine-sewn seam.

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

Sew the hole first. Washing before you sew can cause the edges of the hole to fray more, making it harder to close neatly. After you've sewn it, wash the shirt inside out on a gentle cycle to avoid putting stress on the repair while it's new.

What's the difference between a running stitch and a backstitch?

A running stitch is faster but less strong — the needle goes in and out in a straight line, leaving small gaps between stitches. A backstitch overlaps itself and creates a solid line that won't pull apart under stress. Use a running stitch for patches and decorative work, and a backstitch for seams or areas under tension.
