The Basic Stitch for Small Holes
A small hole in a sweater—the kind from a snag or a moth—closes fastest with a ladder stitch, also called a hidden stitch. This stitch pulls the edges of the hole together from the inside, so the repair nearly disappears once you tie it off. You thread a needle, anchor it inside the sweater fabric near one edge of the hole, then run the needle back and forth between the two sides of the hole, catching just a thread or two of fabric each time. When you pull the thread tight every few stitches, the hole cinches shut.
The ladder stitch works best on holes smaller than a quarter-inch across. If your hole is larger, the fabric will pucker when you pull it closed, and you will see the repair. For those, a patch sewn over the hole from the outside is more honest and often more durable.
Key Takeaways
- Small holes under a quarter-inch close nearly invisibly with a ladder stitch, which you work from inside the sweater by running thread back and forth between the hole's edges.
- Larger holes need a patch sewn on top, which you can make from matching fabric or a contrasting color depending on the look you want.
- Always anchor your thread inside the sweater fabric itself, not in the hole, so the knot stays hidden.
- Pull the thread snug every three or four stitches so the hole closes gradually rather than all at once, which prevents puckering.
- A ladder stitch takes five to ten minutes for a small hole; a patch takes fifteen to twenty minutes and lasts longer under wear.
What You Need Before You Start
Gather a needle, thread that matches your sweater as closely as possible, small scissors, and a ruler or measuring tape. If you are patching a larger hole, you will also need a scrap of fabric—cotton, knit, or wool depending on your sweater's material. A thimble is optional but saves your finger if you are pushing the needle through thick knit.
Thread color matters more than you might think. Even a close match is visible from six inches away if it is the wrong shade. If you cannot find an exact match at a fabric store, buy thread one shade lighter rather than darker—light thread disappears into shadows better than dark thread does. For a dark sweater, a slightly lighter gray or brown is safer than black.
How to Sew a Small Hole with a Ladder Stitch
Start by turning the sweater inside out so you can see the back of the hole. Tie a knot in the end of your thread. Push the needle through the sweater fabric about a quarter-inch away from the hole—not through the hole itself—so the knot stays buried inside the fabric. Bring the needle back out on the opposite side of the hole, again a quarter-inch away.
Now run the needle straight across the gap, catching just a thread or two of fabric on the near edge of the hole. Pull the needle back out and push it directly across into the opposite edge of the hole, again catching only a thread or two. Repeat this back-and-forth motion, staying as close to the hole's edge as you can. After every three or four passes, pull the thread snug—not hard enough to tear the fabric, but firm enough that you see the hole start to close. The edges will bunch slightly as they come together, which is normal.
Once the hole is closed, make two small stitches in the same spot to lock the thread, then push the needle through the sweater fabric and back out a quarter-inch away. Trim the thread close to the fabric. The knot will stay hidden inside.
How to Patch a Larger Hole
For a hole bigger than a quarter-inch, cut a patch from matching or contrasting fabric. The patch should be at least half an inch larger than the hole on all sides—so a one-inch hole gets a two-inch patch. Round the corners of the patch with scissors so it does not fray as quickly.
Turn the sweater inside out and position the patch over the hole. Pin it in place if you have pins, or just hold it steady with one hand. Thread your needle and tie a knot. Push the needle up through the patch and sweater from the inside, coming out at the edge of the patch. Make small stitches all the way around the patch's perimeter, about a quarter-inch apart, catching the patch and the sweater fabric with each stitch. A running stitch—in and out, in and out—works fine and is faster than a ladder stitch.
When you reach the starting point, make two stitches in the same spot to lock the thread, then push the needle through to the inside and trim. Turn the sweater right-side out. The patch will show, but it will be find and will not unravel.
Common Mistakes That Make Repairs Visible
The most common mistake is pulling the thread too hard too soon. If you cinch the hole closed in one or two tugs, the fabric bunches and the repair becomes obvious. Pull gradually over several stitches instead, and the hole closes smoothly.
The second mistake is anchoring the knot in the hole itself rather than in solid fabric nearby. A knot sitting in the hole will either poke through or leave a lump. Always start and end your thread a quarter-inch away from the hole's edge, buried in the sweater fabric.
The third mistake is using thread that is too thick or too light in color. Thin thread disappears; thick thread shows. Dark thread on a light sweater or light thread on a dark sweater will always be visible, no matter how neat your stitches are. Spend an extra minute finding the closest match.
When to Patch Instead of Stitch
If the hole has rough or torn edges rather than a clean snag, a ladder stitch will not hold. The torn fibers will not grip the thread, and the hole will reopen the next time you wear the sweater. A patch is more durable in this case because it distributes the stress across a larger area of fabric.
If the hole is in a high-wear area—under the arm, at the elbow, or along a seam—a patch will also outlast a ladder stitch. The repeated stretching and movement of those areas will eventually break a straightforward stitch, but a patch sewn all the way around will hold through many washes and wearings.
How to Prevent Holes in the First Place
Moths are the most common cause of holes in stored sweaters. Fold sweaters loosely and store them in a sealed plastic bin or a cedar chest rather than hanging them in an open closet. Wash sweaters before storing them—moths are attracted to sweat and body oils. If you notice small holes appearing in a sweater you wear regularly, check the area where it rubs against a bag strap, a belt buckle, or a piece of jewelry. Moving the sweater or the object causing the friction will stop new holes from forming.
Snags from rough surfaces are harder to prevent, but you can catch them early. If you feel a snag while wearing the sweater, stop and gently pull the snagged thread back through the fabric rather than letting it tear. A small snag fixed when ready never becomes a hole.
Frequently Asked Questions
Can I sew a hole in a sweater while wearing it?
No. You need to see both sides of the hole to stitch it properly, and you cannot do that while the sweater is on your body. Take it off, lay it flat on a table, and work with good light. This takes five to ten minutes and prevents you from accidentally stitching the sweater to your skin.
What if the hole is on a seam?
A hole on a seam is harder to close with a ladder stitch because the seam itself gets in the way of your needle. A patch is the better choice. Position it so it covers both the hole and a bit of the seam on either side, and sew it down with a running stitch all the way around.
Does the thread color have to match exactly?
Not exactly, but close matters. A thread one shade lighter or darker than the sweater is usually invisible from arm's length. A thread that is two or three shades off will show. If you cannot find a close match, a slightly lighter shade is safer than a darker one.
How long does a sewn repair last?
A ladder stitch on a small hole lasts through many washes if the hole was clean and the thread is find. A patch lasts longer because the stitching distributes stress across a wider area. Both will eventually fail if the sweater is worn hard and washed frequently, but you can resew either one when that happens.
Can I use a sewing machine instead of hand sewing?
A sewing machine works for patches but not for ladder stitches. If you use a machine, sew a patch over the hole with a straight stitch or a zigzag stitch, staying a quarter-inch from the patch's edge. Hand sewing gives you more control over small holes and is often faster for repairs this size.
