It’s a waste to discard expensive running socks simply because of a small hole. I had a collection of six pairs with various holes and thin spots. To prevent these socks from ending up in the bin and to save money, I decided to learn the art of darning. This post will guide you through the technique of darning to repair your socks.
🧦 What is Darning?
Darning is the art of repairing holes or worn areas in knitted materials by interweaving new threads. Traditionally done by hand, darning can also be accomplished using a sewing machine. This age-old practice is commonly used to mend socks and other garments.
The process involves creating a framework of running stitches, reversing direction at the end of each row, and then filling in the framework with perpendicular stitches. This technique is an excellent alternative to patching holes in applications where patches are impractical. Socks, in particular, benefit greatly from darning as patches can create hot spots or blisters.
The initial series of running stitches is known as the warp, while the perpendicular stitches that fill in the framework are called the weft.

❓ Why Darn?
Darning offers significant cost savings! Running socks can be pricey; a quality pair of Injinis, for example, costs $35. I have several pairs that are gradually deteriorating, often developing holes near the ball of my foot. It’s a shame to discard a sock that’s still mostly intact.
Ziggy has been darning his socks for years and claims to extend their lifespan by an entire year.
Beyond the financial benefits, I’ve found the process of darning to be incredibly relaxing. Listening to an audiobook or podcast while darning provides a tranquil way to rest and recover from intense running.
✂ Equipment Required
| Item | Cost | Source |
|---|---|---|
| Darning mushroom | $11 | Spotlight |
| Darning needles | $5.50 | Spotlight |
| Darning thread | $8.50 | Spotlight |
| Rubber bands | free | Get off a bunch of spring onions |
| Scissors | free | Use the ones you already own |
| Total cost | $25 |

🧵 How to Darn Socks
- Turn the sock inside out
- Place the darning mushroom inside the sock
- Tighten the sock over the mushroom and fix with a rubber band


- Cut off any excess edges to clean up the edges of the hole
- Cut a decent length of thread and thread the needle
- Start away from the hole and begin the warping stitches, don’t put a knot at the end of the thread

7. Once the the hole is completely covered begin the wefting stictches by turning 90 degrees and stitching across what you’ve just done. Try to go above and below all of the warping stitches, especially when you are covering the hole

8. Continue the wefting stitches till you are on the other side of the hole
9. Cut the excess thread and turn the sock back the right way out and you are done!!

📊 My Results so Far
I’ve successfully repaired two pairs of socks. With the necessary equipment and skills in hand, I’m eager to tackle the remaining five pairs. My experience running in these repaired socks has been seamless; they’re comfortable, and the darning stitches have held up well.
Considering each pair of socks to be worth $35, repairing seven pairs will save me a substantial $245. The initial investment of $25 for the darning equipment will quickly be recouped, and the skill I’ve acquired will benefit me for years to come.
Before discarding your old socks, I encourage you to consider learning to darn. Not only will you gain a valuable new skill, but you’ll also bring new life to your beloved toe socks. This sustainable practice can help you run longer for less.

Any ideas for what to use as a mushroom if your hole is in the toe part of the sock?
Hi Danielle, I am yet to try darning the toes, but my housemate has made attempts at it. He said he finds whatever he can that fits in the toe. I am thinking anything slightly rounded like the handle of a hair brush or similar. He reported having great difficulty with the toes though. Good luck with it
For the little toes I used the case for a pair of loop earplugs. It’s a hard smooshed ball shape. Worked brilliantly!
