How to Repair a Hole in Your Favorite Sweater
A hole doesn't mean the end of a sweater you love—it means an afternoon with a needle and thread. We'll walk you through three repair methods, each suited to different damage patterns.
5 min read · IrisA hole in your favorite sweater feels like a small tragedy. But unlike a torn seam, which signals structural failure, a hole in the knit itself is often fixable—especially if you catch it early. The method you choose depends on the hole's size, location, and whether you care more about invisibility or durability.
We've outlined three approaches: invisible darning for small holes in solid colors, needle-felting for pilled areas, and a reinforced patch for larger damage or high-wear zones. Each takes under an hour and requires only basic supplies you probably already own.

What you'll need.
- 01Needle (size 6–8 for most sweaters)
- 02Matching yarn or thread
- 03Felting needle (barbed, for needle-felting method)
- 04Scissors
- 05Pins
- 06Pillow or foam pad for support
- 07Matching fabric or thin knit (for patches)
- 08Magnifying glass (optional)
- 09Mild detergent for finishing wash
Step one · 5 minutes
Assess the damage
Hold the sweater up to natural light and examine the hole from both sides. Note its size (pinhole, dime-sized, or larger), shape (round, jagged, or elongated), and location (seam, body, or cuff). Check whether the surrounding fabric is pilled or felted—this affects your repair method. Small, clean holes in solid-colored sweaters are ideal candidates for invisible darning. Larger holes or those near seams may need a patch instead.
Don't wash the sweater before repairing it; clean fabric is harder to work with and more prone to unraveling.

Gather matching yarn
Find yarn that matches your sweater's fiber content and color as closely as possible. If you have the original ball, use that. If not, unravel a small section from an inconspicuous seam or cuff to get an exact match. Test the yarn on a hidden area first—some dyes shift slightly under different lighting. For a perfect match on patterned sweaters, use yarn from the dominant color or blend two shades together.
Bring your sweater to a yarn shop and hold it under their lighting; colors look different at home versus in-store.

Darn small holes with the ladder stitch
Thread a needle with 18 inches of yarn and knot one end. Insert the needle from inside the sweater, about half an inch from the hole's edge. Weave horizontally across the hole, going under and over the vertical knit loops, then reverse direction on the next row. Work methodically, keeping tension consistent—too tight and you'll pucker the fabric; too loose and the repair won't hold. Once you've filled the hole, weave the yarn back through existing stitches to anchor it, then knot and trim.
Work on a flat surface with the sweater stretched gently over a pillow or book; this keeps the fabric stable and prevents distortion.
Step four · 10 minutes
Needle-felt pilled or fuzzy holes
If the hole is surrounded by pilling or the fabric is already felted, needle-felting works better than darning. Use a felting needle (a barbed needle designed for this purpose) to repeatedly poke the surrounding fibers inward, matting them together to close the gap. Work in a circular motion around the hole, gradually moving toward the center. This method is forgiving and works on any sweater color or pattern. Stop when the hole is visibly smaller and the surrounding area feels solid.
Needle-felting needles are fragile—work slowly and support the sweater from underneath to avoid breaking the needle.
Step five · 10 minutes
Patch larger holes from the inside
For holes larger than a quarter or damage near seams, a reinforced patch is more reliable. Cut a piece of matching fabric (or thin knit) roughly one inch larger than the hole on all sides. Pin it behind the hole from the inside of the sweater, then whip-stitch around the perimeter using matching yarn. Make small, tight stitches about an eighth inch apart. Once secure, you can optionally darn over the top of the patch for extra reinforcement, especially in high-wear areas like elbows.
Use a fabric with some stretch—cotton jersey or a thin knit works better than woven cotton, which can feel stiff against your skin.
Step six · 5 minutes
Finish and inspect
Once your repair is complete, gently hand-wash the sweater in cool water with mild detergent to set the stitches and remove any loose fibers. Lay it flat to dry. Inspect the repair from both sides—the inside should show your work clearly, while the outside should blend seamlessly (or be acceptably visible, depending on your method). A successful repair should feel as sturdy as the surrounding fabric and not create any puckering or distortion.
Don't machine-wash or dry-clean immediately after repair; let the stitches settle for at least one wear cycle first.
How to know your repair will hold
A successful sweater repair feels invisible or intentional, depending on your method. The repair should move with the fabric, not against it, and shouldn't create stiffness or puckering. If you've darned correctly, the outside should show minimal evidence of the work. If you've patched, the inside seam should be secure and the outside should look deliberate.
Questions at the mirror.
The hole is growing or unraveling at the edges. What do I do?
Stop the unraveling immediately by securing the edge with a whip stitch before attempting any repair. Work from the inside, stitching around the perimeter of the hole to anchor loose loops. Once the edge is stable, proceed with your chosen repair method.
I can't find yarn that matches exactly. Can I blend two colors?
Yes. Thread your needle with two strands of slightly different shades and work with them together. The blended effect often looks more natural than a single mismatched color, especially on heathered or tweedy sweaters.
My darning looks visible on the outside. Is that a problem?
Not necessarily. Visible darning is a legitimate repair aesthetic—it shows the sweater has a history and you care enough to fix it. If invisibility matters to you, try needle-felting instead, which tends to blend better on the surface.
The sweater is cashmere or merino. Are the methods different?
The techniques are the same, but work even more carefully with delicate fibers. Use a smaller needle, lighter tension, and consider needle-felting over darning—it's gentler on luxury knits. Test on a hidden seam first.
