Merino helps regulate temperature, making it a natural choice for cosy everyday socks and lightweight layers.
Crucci 4 Ply Sock Yarn
Soft merino comfort, built to handle life inside a shoe
Crucci 4 Ply Sock Yarn pairs soft superwash merino with hard-working nylon, giving hand-knit socks the warmth and comfort you want with extra resilience where heels, toes and soles take the most wear. Each generous 100g ball contains approximately 400m for socks, shawls and other fine-gauge projects.
- 75% superwash merino brings natural warmth, breathability and softness.
- 25% nylon reinforces the yarn for better abrasion resistance and shape retention.
- Approximately 400m per 100g gives useful project mileage from one ball.
- Solid and multicolour options cover classic socks, colourwork and lively self-patterning effects.

Comfort where you feel it, reinforcement where you need it
Pure merino is beautifully soft, but socks face repeated friction from shoes and daily wear. Crucci balances that comfort with nylon so the finished fabric is better suited to hard-working feet without losing the warmth and natural feel knitters value.
Nylon adds strength and abrasion resistance, especially useful through the heel, sole and toe.
The superwash wool blend can be machine washed when the ball-band care instructions are followed.
Why the nylon matters
A better match for socks than softness alone
The 25% nylon is not filler. It is the hardworking part of the blend, helping fine stitches tolerate rubbing and repeated use. The 75% merino remains the dominant fibre, so the fabric still feels warm, flexible and comfortable against the skin.
- More resilient through high-friction areas
- Helps socks keep their shape through repeated wear
- Still soft enough for shawls, gloves and lightweight garments

Self-patterning interest or complete colour control?
Choose multicolour
Ideal when you want changing colour, stripes and marled effects to emerge from one ball without joining multiple yarns. The finished sequence depends on the width and shape of your knitting.
Choose solid
Best for cables, lace, stitch definition, colourwork and coordinated contrast details. Pair a solid with a multicolour shade for cuffs, heels and toes that look intentionally finished.
Fine-gauge projects with warmth and useful resilience
Everyday socks
Use the merino-nylon blend for comfortable socks with reinforcement through hard-wearing areas.
Shawls and wraps
Approximately 400m per ball gives generous length for lightweight lace, textured and colour-changing accessories.
Gloves and baby knits
Soft merino warmth and machine-wash practicality suit frequently worn small projects.
Light garments
Choose solid shades for stitch detail or multicolours for lively fabric, then calculate total metreage carefully.
Fit begins with the swatch
Sock gauge is a performance decision
Crucci recommends 2.25mm to 3.25mm needles. Published references place this yarn around 28 to 32 stitches per 10cm, but your pattern, needle size and knitting style determine the correct target. For socks, a firm fabric usually wears better than a loose one.
- Follow the gauge specified by your chosen pattern
- Swatch in the round when the project is knitted in the round
- Wash and dry the swatch before measuring
- Use the pattern's intended negative ease for a secure fit
Important: needle size is only a starting point. Two knitters can use the same needles and produce different fabric. Measure the washed swatch, not the label alone.
Is one 100g ball enough for a pair of socks?
Many adult sock patterns are designed around one 100g ball of 4 ply sock yarn, and approximately 400m is a familiar starting quantity. Exact use still changes with foot size, leg length, stitch pattern, tension and whether contrast yarn is used.
Check the pattern
Use its required metreage for the exact size and leg length you plan to knit.
Compare with 400m
Each ball contains approximately 400m. Allow for swatching and any design changes.
Order together
For multiple balls, buy the full project quantity at once and match dye lots where possible.
For matching multicolour socks: begin each sock at the same point in the colour sequence. This may use extra yarn, so build a margin into your plan.

Help hand-knit socks keep their shape and colour
Hand wash or use a suitable gentle machine cycle, following the instructions on the ball band.
This reduces surface friction during washing and helps protect the visible outer fabric.
Avoid bleach, high heat and tumble drying. Do not wring or aggressively spin the fabric.
Reshape while damp and allow the project to dry naturally away from direct heat and strong sun.
Best practice: the ball band is the final care authority for your shade and production batch. A gentle wash extends the life of any hand-knit sock.

Crucci 4 Ply Sock Yarn FAQs
Is this yarn suitable for socks?
Yes. It is specifically built as a sock yarn, combining 75% superwash merino for warmth and comfort with 25% nylon for added strength and abrasion resistance.
Will one ball make a pair of adult socks?
One 100g ball with approximately 400m is enough for many adult sock patterns, but exact use depends on size, leg length, gauge and design. Always check the pattern metreage.
What is the difference between the multicolour and solid shades?
Multicolour shades change colour as you knit and can create stripes or marled effects. Solids provide even colour and clearer stitch definition, and they are useful for contrast cuffs, heels and toes.
Will two multicolour socks look exactly the same?
Not automatically. Start the second sock at the same point in the colour sequence for the closest match. The effect also changes with stitch count, tension and sock size.
Is Crucci 4 Ply Sock Yarn machine washable?
Yes, it is a superwash blend. Use lukewarm water and a gentle wool-appropriate cycle, then dry flat in the shade. Do not tumble dry, and follow the ball-band instructions.
Can I use it for shawls or garments?
Yes. Its soft merino content and 400m length make it useful for shawls, gloves, baby knits and lightweight garments as well as socks. Swatch for drape and gauge.
Can I crochet with it?
Yes. Choose a hook that creates the intended density and drape, then wash and measure a swatch before starting the full project.
What needle size should I use?
Crucci recommends 2.25mm to 3.25mm as a starting range. Follow your pattern and washed gauge swatch for the final choice, especially when knitting socks.
Why might the colour look different on my screen?
Displays and lighting reproduce colour differently, and dye lots may vary slightly. Use the shade number, shade name and official photograph together when selecting.
