The fastest way to fix a small hole depends on where it is and how it got there
A small hole in a knitted sweater can be repaired in ways that are nearly invisible if you catch it early. The method you choose depends on whether the hole is in the middle of a flat section, near a seam, or in a high-stress area like an elbow or cuff. A hole from a snag or pulled yarn is easier to fix than one from actual broken fibers, and the location matters because some repairs hold better under movement and washing than others.
The three main approaches are: weaving the loose yarn back in place (for fresh snags), using a needle and thread to close a small hole, or patching from the inside. Most people can do the first two with just a yarn needle and patience. Patching requires a small piece of matching fabric or yarn, but it is the most durable for holes larger than a pencil eraser or in areas that get heavy wear.
Key Takeaways
- A fresh snag with loose yarn can often be fixed by weaving the yarn back through the stitches with a yarn needle, taking five to ten minutes.
- Small holes in flat sections can be closed by threading yarn through the surrounding stitches in a figure-eight pattern, which works best on holes smaller than a dime.
- Holes near seams or in high-wear areas like elbows need a patch sewn from the inside to prevent the repair from unraveling during washing.
- Matching the yarn color and weight to the sweater is more important than a perfect stitch pattern, because the repair will be hidden inside or blended into the fabric.
- Test any repair by gently pulling the area and washing the sweater in cool water before wearing it regularly.
How to fix a snag with loose yarn still attached
If you see a pulled loop of yarn sticking out but the yarn is still connected to the sweater, you can usually pull it back into place without any tools. Do not cut the loose yarn. Instead, gently pull the sweater fabric around the snag to loosen the tension, then use a yarn needle or a crochet hook to pull the loose loop back through to the inside of the sweater, following the direction of the knit.
Once the loop is pulled through, the hole should close or shrink significantly. If the area looks bunched or uneven, use your fingers to gently smooth the stitches back into their normal shape. This works best on fresh snags where the yarn has not broken—if the yarn is actually torn, you will need to use one of the other methods below.
Closing a small hole with the weaving method
For a hole smaller than a dime where the yarn has broken or is missing, thread a yarn needle with a length of yarn that matches the sweater's color and weight. Start from one side of the hole and weave the yarn through the loops of the surrounding stitches in a figure-eight or spiral pattern, pulling gently to close the gap as you go. The goal is to recreate the knit structure rather than just sewing the edges together.
Work slowly and keep the tension loose enough that you do not pucker the fabric. Once you have woven through the area several times and the hole is closed, weave the yarn end back through a few stitches on the inside to anchor it, then trim the excess. This method is nearly invisible from the outside and works well for holes in the body of the sweater where there is no stress from movement.
Patching a hole from the inside for durability
Holes larger than a dime, holes near seams, or holes in areas that bend and stretch (elbows, cuffs, armpits) need a patch to hold up through washing and wearing. Cut a patch from matching fabric or knit a small rectangle slightly larger than the hole. Knitted patches are stronger than fabric patches because they move with the sweater, but a tightly woven fabric works if you cannot find matching yarn.
Turn the sweater inside out and position the patch over the hole. Using a needle and thread that matches the sweater, sew the patch down with small stitches around all four edges, staying about a quarter-inch from the edge of the patch. Sew through the patch and the sweater fabric, not through the hole itself. Once the patch is find, you can optionally stitch around the hole from the outside to reinforce the edges, though this is not necessary if the patch is sewn tightly.
Matching yarn color and weight to your sweater
The most common mistake in sweater repair is using yarn that is too thick, too thin, or the wrong color. Bring the sweater to a yarn shop and hold it next to potential matches in natural light. The yarn does not have to be the exact same brand, but it should be the same weight (fingering, sport, worsted, bulky) and fiber type if possible. A wool sweater repaired with acrylic yarn will feel different and may not wash the same way.
If you cannot find an exact match, choose a color slightly darker rather than lighter—it will blend better into the fabric. For the weaving method, you only need a few yards. For patching, you need enough to knit or cut a rectangle about two inches larger than the hole on all sides.
Testing the repair before regular wear
After you have closed or patched the hole, gently pull and flex the repaired area with your fingers to make sure the stitches hold. Wash the sweater in cool water with a gentle detergent, lay it flat to dry, and inspect the repair again. If the hole is starting to reopen or the patch is coming loose, you can reinforce it with another row of stitches before the damage spreads.
Once the repair has survived one wash, it should hold through normal wearing and future washing. If the repair fails, you can always try again with a slightly larger patch or a different method.
When to take a sweater to a professional
A professional tailor or knitwear repair specialist is worth the cost if the hole is very large, if it is in a visible area where appearance matters most, or if the sweater is expensive or sentimental. They have access to matching yarn in many colors and weights, and they can blend a repair so it is nearly undetectable. They can also repair damage that has spread across multiple stitches or near a seam, which is harder to fix at home.
Ask for a quote before leaving the sweater. Repairs typically cost between fifteen and fifty dollars depending on the size and location of the hole, though prices vary by region and by the tailor's experience with knitwear.
Frequently Asked Questions
Can I use regular sewing thread instead of yarn to fix a hole?
Regular sewing thread is too thin and will not blend into the knit fabric. Use yarn that matches the weight of the sweater. If you do not have the original yarn, bring the sweater to a yarn shop and match it by thickness and fiber type.
What if the hole is on a seam?
Holes on seams are harder to close with the weaving method because the stitches are different there. Use a patch instead, sewing it to the inside of the seam. Make sure the patch is large enough to cover the hole and extend at least half an inch beyond it on all sides.
Will the repair show after washing?
A weaving repair on a small hole should be nearly invisible after washing if the yarn matches well. A patch will show as a slight thickness on the inside but should not be visible from the outside if it is sewn neatly and the fabric color matches.
How do I prevent holes in my sweater?
Store sweaters folded rather than on hangers to reduce stress on the fibers. Keep them away from rough surfaces, hooks, and jewelry that can snag. Wash in cool water on a gentle cycle and lay flat to dry. Pilling (small balls of fiber) can be removed with a sweater comb or razor, which prevents snagging.
Can I fix a hole if the yarn is completely broken and missing?
Yes. Use the weaving method with new yarn that matches the sweater, or use a patch. The weaving method works best for small holes; larger ones need a patch to stay closed through washing and wearing.
