Methods for mending sweaters & knitwear
A bit about knits…
Understanding the basics of fabric structure & mending techniques will make it easier to find the right repair resources to solve your problem. If you’re already familiar with textiles and mending, you can skip down to the DIY & professional repair resources!
Most fabrics fall into two categories:
Wovens
Knits
Wovens (left) are made by interlacing two or more threads at right angles to one another. Woven fabrics do not have much stretch (unless the threads themselves are inherently stretchy like spandex), and woven fabric is typically used to make things like dress shirts, jeans, and bedsheets.
Knits (right) are made of a single strand of fiber / yarn, that is looped onto itself creating an inter-meshing of loops. Due to their looped structure, knit fabrics are generally stretchy. T-shirts are usually made of knit fabric - if you look really closely at your T-shirt (or sweater, or hoodie, or socks) you can see tiny columns of loops.
Mending methods
Two of the most popular ways to mend knit fabrics are:
Woven darning
Swiss darning, often called ‘invisible mending’ for knits
Woven darning (left) involves creating a patch of woven fabric to ‘fill’ or cover a hole. Woven darning can be used to repair both knit fabrics and woven fabrics.
Swiss darning (right) follows the looped structure of the knit, essentially re-knitting the hole, creating an ‘invisible’ look when using matching yarn.
In either case, you can choose to use an exact or close yarn match to achieve an unobtrusive or ‘invisible’ repair.
Or, you can take a visible / decorative mending approach and use color, shape, and technique to treat your repairs as new design element to your garment!

Classes / Workshops & Meetups
Nothing beats hands-on instruction - most of these skills ultimately take repetition to get good, and having a person available to watch & correct your form speeds things up considerably.
I’ve also found that the act of committing to a class / meetup (and therefore dedicating specific time to mending) is the ONLY way I’ve managed to make a dent in my own repair pile.
Most darning classes I’ve come across are focused on general purpose woven darning (works for knits, thin wovens). Some darning classes specialize in socks, or denim. I’m focusing on repairing knits & socks here and will do a separate series in the future covering various ways to repairing denim! Also - classes focused on Swiss darning are very rare, but I’ve called out the ones I know, below.

Books & Guides
There are tons of books, guides, and videos out there you can reference if you’re learning how to darn (or want to refresh and / or practice your skills after taking a class). Here are a few good ones that I have / follow / recommend - and now that you know the terminology, you can easily search for others to suit your needs!
Book: Visible Creative Mending for Knitwear by Flora Collingwood-Norris - I purchased this book last year, it’s a fantastic guide to knitwear-specific mending & darning techniques, with beautiful examples of visible mending
Video Tutorial: Collingwood-Norris also offers pre-recorded darning tutorials & classes
Book: I love that the english edition of Hikaru Noguch’s Darning, Reapir, Make, Mend Book comes with a small ‘starter kit’ of needles, yarn, and a yarn threader
Newsletter: friend Danielle Urban recently wrote a great ‘how to’ guide to darning for her newsletter Front Porch Threads - includes videos (I always find helpful to watch & rewatch when I’m learning a new fiber skill)
Book: A newsletter about darning wouldn’t be complete without mention of artist Celia Pym. Her book On Mending is less a guide than a meditation on repairing damaged garments. I wish I could attend her exhibit Socks: The Art of Care and Repair, on view in Greenwich, UK through March 30th
Newsletter: In putting together this newsletter, I came across Skye Pennant’s slow stitch club newsletter and (the same Slow Stitch Club mentioned under classes above and professional mending services below). Also linking her YouTube channel here, with super helpful tutorials, including advanced techniques like darning cuffs and swiss darning.
Instagram: there are a bunch of darners / menders worth following for inspiration & instruction!
@alexandrabrinck - for fantastic up-close videos of swiss darning
@visible_creative_mending (Collingwood-Norris)
I’m sure there are tonsss more (and I don’t even really use TikTok but I’m guessing there are good videos & resources there as well) - would love to hear who you all follow too!
Find a professional to mend your sweaters & knits
If you don’t have the time to mend things yourself, I’ve rounded up a number of professional repair services, focusing on those that specifically offer darning / knitwear repair.
Many of these providers offer a wide range of clothing repair services, so consider them your answer to that pile of damaged & ‘not quite right’ clothes sitting in the back of your closet…

I hope this guide is useful as you contemplate the holes you’ve found and whether / how to repair them. I would love to continue adding to this list of resources - if you know of darning resources and repair providers that I have missed, please let me know so that I can update & include them here!
I’m doing exactly this for my garden sweater, which got attacked by moths! (We did, at last, solve the moth problem.)
This is such an incredible resource Anne! So happy to be included in amongst so many great repair artists - thank you :)
