To repair holes in recycled wool clothing, match the method to the damage: darn small holes with wool yarn, patch larger ones from the inside, and use needle felting where you want an almost invisible fix. Recycled wool has shorter fibres than virgin wool, so work gently, keep stitches loose and use a yarn of similar weight. With a needle, some thread and twenty minutes, most knitwear can go back into rotation.
Why recycled wool needs a lighter touch
Recycled wool is made by breaking down existing wool garments or offcuts and re-spinning the fibres. The process shortens the fibres, which can make the finished knit slightly less elastic and quicker to pill than wool spun from new fleece. In practice that means two things for repairs: stitches pulled too tight will pucker the surrounding knit, and fragile edges around a hole may need reinforcing before you close it.
The same advice applies to most knitwear, including cotton and cotton-blend knits. A well-made knit is worth repairing, and a neat mend often becomes part of the character of a piece you have worn for years.
Choose the right repair method
| Damage | Best method | Visibility | Time |
|---|---|---|---|
| Pinholes and moth holes under 5 mm | Needle felting or a few duplicate stitches | Near invisible | 10 minutes |
| Holes 5 mm to 3 cm | Darning | Subtle, or deliberate in a contrast colour | 20 to 40 minutes |
| Holes over 3 cm, worn elbows | Patch from the inside or a sewn-on elbow patch | Visible, can look intentional | 30 to 60 minutes |
| Dropped or laddered stitch | Pick up with a crochet hook and secure | Invisible if caught early | 10 minutes |
What you need
- A blunt-tipped darning or tapestry needle
- Wool yarn in a matching weight and colour (or a contrast colour for visible mending)
- A darning mushroom, a tennis ball or a smooth jar to hold the knit taut
- Small sharp scissors
- For felting: a felting needle, a foam pad and loose wool roving
How to darn a hole: step by step
- Prepare the area. Turn the garment inside out and trim any loose, fluffy fibres around the hole. Do not cut into intact stitches.
- Stretch it over a form. Place the darning mushroom or ball under the hole so the knit is flat and gently taut, not stretched.
- Outline a frame. Using running stitches about 1 cm outside the hole, sew a square or circle around it. This anchors the repair in healthy fabric.
- Lay the vertical threads. Work parallel lines of yarn across the hole from one side of the frame to the other, close together, catching healthy stitches at each end.
- Weave horizontally. Now weave across those lines, over one and under the next, alternating each row, until the hole is filled with a small woven panel.
- Finish and press. Weave the tails into the back for a few centimetres, then press lightly through a damp cloth with a cool iron.
Needle felting for tiny holes
Needle felting is the quickest fix for moth damage. Place the foam pad inside the garment beneath the hole, lay a small wisp of matching wool roving over it and stab repeatedly with the felting needle. The barbs tangle the new fibres into the existing knit. Add more roving in thin layers until the hole is closed, then turn the garment over and lightly felt from the other side. Keep your fingers clear of the needle; it is very sharp.
Patching larger holes and elbows
For bigger holes, cut a patch of knit or felted wool about 2 cm larger than the damage on all sides. Pin it to the inside, then sew round the hole with small whip stitches, keeping tension loose. For worn elbows, sew a suede, leather or wool patch on the outside; it is a classic menswear detail that looks deliberate on a crewneck or cardigan.
Prevent the next hole
- Wash knitwear only when needed, on a cool or wool cycle, and dry flat.
- Store knits clean and folded, never hung, and use cedar or lavender in drawers to deter moths.
- Rotate pieces so no single knit takes all the wear.
- Remove pills with a fabric comb before they loosen surrounding fibres.

If you are replacing a knit beyond repair, look for weight and structure. The BALIVENO Oversized Knit Crewneck Sweatshirt is a 290 gsm cotton-polyester knit with a ribbed collar, and the Baliveno New Heavyweight Crewneck Sweatshirt is 420 gsm in an 85% cotton, 15% polyester blend, with ribbed collar, cuffs and hem. Both are machine washable at 30°C on a gentle cycle, according to their care labels.
Frequently asked questions
Can I repair a wool sweater without sewing?
Yes. Needle felting closes small holes without any stitching, and iron-on knit patches can work as a quick fix, though they are less flexible and may lift after washing.
What yarn should I use to darn recycled wool?
Use a wool or wool-blend yarn of the same thickness as the knit, or slightly finer. Thicker yarn creates a stiff, raised patch that can strain the fabric around it.
How do I know if moths caused the holes?
Moth damage usually shows as several small, irregular holes, often in hidden areas such as under the arms or along the back, sometimes with fine silky residue. Check the rest of your knitwear and clean your drawers if you find it.
