Sock Yarn

Sock yarn is one of the most rewarding yarn purchases you can make — hardwearing, beautifully coloured, and endlessly versatile. Whether you are knitting your first pair of socks or your fiftieth, our collection of sock weight yarns spans merino blends, superwash wools and wool-nylon mixes built to last.

What is the best yarn for knitting socks that will last?

For socks worn regularly in shoes, the best choice is a superwash merino and nylon blend — typically around 75–80% merino and 20–25% nylon. The superwash treatment allows machine washing without felting, and the nylon content reinforces the heel and toe where friction is highest. West Yorkshire Spinners Signature 4 Ply is a popular example widely available in the UK and a consistent performer. Avoid 100% natural fibre yarns for everyday socks unless you are prepared to hand wash carefully and reinforce the heels with a separate strand of nylon reinforcement thread.

What needles do I need to knit socks?

Most sock knitting is done on 2.25mm to 2.75mm needles, depending on your tension and the yarn's recommended size. Socks are traditionally knitted in the round — either on a set of four or five double-pointed needles (DPNs), on a long circular needle using the magic loop method, or on a short 9" circular. Each method produces the same result, so the right choice comes down to personal preference. Many knitters in Scotland and across the UK start with DPNs as they are the most widely taught method, but magic loop has grown in popularity due to the convenience of needing only a single needle. You will also need a cable needle or stitch holders for heel turning, and a blunt-tipped tapestry needle for grafting the toe.

How much sock yarn do I need for a pair of adult socks?

A standard adult-sized sock in a medium foot size (UK 6–8) typically requires 350–400 metres of sock yarn. Most 100g skeins of 4 ply sock yarn contain between 380–425m, meaning one 100g skein is usually sufficient for a pair of socks in a smaller adult size. For larger feet (UK 9 and above) or if you prefer a taller leg, it is safer to purchase two skeins and work both socks from the same dye lot. If you are knitting striped or contrast-heel socks, budget for two separate skeins or colourways accordingly.

Is sock knitting suitable for beginners in Scotland and the UK?

Sock knitting is achievable for beginners but does require basic knitting competence first — specifically, the ability to cast on, knit, purl, and decrease comfortably. If you are completely new to knitting, it is worth working through a simpler project such as a hat or a cowl before tackling socks, as the combination of working in the round, heel turning, and grafting the toe can feel overwhelming when you are still building foundational skills. That said, many knitters across Scotland learn to knit socks as their second or third project with support from a local yarn shop or class, and find the technique clicks quickly with practice. Our guide to how to knit socks is a good starting point if you are ready to give it a go.

Can I use regular 4 ply yarn instead of dedicated sock yarn?

You can knit socks from any 4 ply yarn, but there are practical trade-offs to understand before you do. Dedicated sock yarn — particularly those with 20–25% nylon content — is significantly more durable at the heel and toe than a pure wool or merino 4 ply. A sock knitted in a luxury 100% merino will feel beautiful initially but is likely to develop thin patches or holes at wear points within months of regular use, regardless of how carefully it is knitted. If you want to use a non-sock-specific 4 ply, consider holding a fine strand of reinforcement thread (such as Linea Reinforcement Thread) alongside the yarn in the heel and toe sections. This is a straightforward technique that dramatically improves the lifespan of hand-knitted socks.
