What is acrylic yarn good for? The honest guide — and why Stylecraft Special is the benchmark
Acrylic yarn has a reputation problem. In certain knitting circles it is dismissed as the inferior, synthetic alternative to natural fibre — the yarn you use when you cannot afford wool, or when you do not care enough about quality to reach for something better. This reputation is largely undeserved, and anyone who holds it has probably not worked with a good acrylic yarn recently.
The reality is that acrylic yarn has genuine, specific strengths that natural fibres cannot match, and a good acrylic — particularly a premium acrylic like Stylecraft Special — is an excellent choice for a wide range of projects. This is not an argument that acrylic is better than wool. It is an argument that acrylic is better than its reputation, and that for certain projects and certain purposes it is the right choice rather than the compromise choice.
We stock Stylecraft Special DK at £3.15 per 100g ball in 43 colourways, and Stylecraft Special Chunky at £3.15 per 100g ball in 15 colourways, at Craft and Canvas.
What acrylic yarn actually is
Acrylic yarn is made from synthetic polymer fibres — polyacrylonitrile — that are extruded as continuous filaments and then cut and processed to behave like natural fibre. The process has been refined over decades, and modern premium acrylic yarn is quite different from the scratchy, stiff, slightly petrochemical-smelling acrylic of earlier generations.
The fibre itself is lightweight, resilient, and takes dye extremely well — which is why acrylic yarns are available in such extensive colour ranges with such reliable consistency between dye lots. The colour you buy today will match the colour you buy next month in a way that natural-fibre yarns with their inherent variability cannot guarantee.
What acrylic yarn is genuinely good for
Blankets and afghans. This is arguably the single best use of a quality acrylic DK or chunky. A large blanket requires a large quantity of yarn, and the cost of producing a full-size blanket in wool or alpaca quickly becomes significant. A Stylecraft Special DK blanket costs a fraction of an equivalent wool project, machine washes at any temperature, survives daily use without deterioration, and will not felt if someone accidentally puts it in a hot wash. For a blanket that will be used and washed regularly — a baby blanket, a sofa throw, a gift that will genuinely be lived with — acrylic is not the compromise choice. It is the sensible one.
Toys and amigurumi. Soft toys and crocheted amigurumi figures need to be washable, durable, and safe — and they need to hold their shape under the stuffing pressure that plush toys experience. Acrylic excels on all three counts. It does not felt, it survives repeated washing at high temperatures, and it has the firmness of structure that holds a crocheted toy animal together over years of use. Wool amigurumi, however charming, carries the risk of felting and is not appropriate for anything that needs to be machine washed for hygiene reasons.
Children's garments. Garments for children — particularly young children — need to survive frequent washing, sometimes at higher temperatures than adults' clothing. Acrylic handles this without complaint. It does not shrink, does not felt, does not require delicate handling, and retains its shape and colour through many washes. A hand-knitted jumper in Stylecraft Special DK will outlast many machine-made alternatives.
Gifts for people who machine wash everything. The handmade gift question: what if the recipient washes it incorrectly? With a pure wool garment, incorrect washing can be catastrophic — felting is irreversible. With a quality acrylic, the worst outcome of a hot machine wash is a slightly misshapen item that bounces back in wearing. This is not a small consideration when knitting gifts.
Large colourwork and striped projects. The extensive, consistent colour range of Stylecraft Special DK — 43 colourways all available at the same price point — makes it one of the best yarns available for colourwork blankets, striped projects, and any project where matching specific colours reliably and affordably across large quantities of yarn matters. The consistency of the acrylic dye process means colour 1002 Black today will be the same Black in three months when you need another ball.
Beginner projects. Smooth, consistent, affordable, and widely available in any colour a new knitter or crocheter might want — Stylecraft Special DK is the yarn most UK knitting teachers recommend for beginners, and for good reason. The even twist makes stitches easy to see and count, the price makes practice pieces affordable, and the wide availability means it is easy to find.
Crochet. Cotton and acrylic are the two fibres that suit crochet best — the inelasticity of both (in contrast to wool's natural stretch) means stitches sit firmly and clearly where they are placed, and crocheted fabric in acrylic has a clean, structured quality that suits bags, home accessories, and amigurumi particularly well.
What acrylic yarn is not as good for
Honesty requires acknowledging the limitations alongside the strengths.
Warmth. Wool insulates through trapped air in its naturally crimped fibres. Acrylic is warmer than cotton but not as warm as wool, alpaca, or mohair for equivalent weight and thickness. For a garment intended specifically for warmth in cold conditions, wool has a genuine functional advantage.
Breathability. Natural fibres absorb and release moisture — wool in particular is remarkably good at this. Acrylic does not absorb moisture in the same way, which can make it feel slightly clammy in warm conditions or during active wear. For summer garments, cotton is considerably better than acrylic.
Feel against sensitive skin. Even premium acrylic can feel slightly different from the softest natural fibres against very sensitive skin — though the gap between a premium acrylic and a standard wool has narrowed considerably. Stylecraft Special is notably soft for an acrylic and is well tolerated by most people, but for someone with significant wool or synthetic sensitivity, the difference matters.
The intangible quality of natural fibre. This is harder to quantify but worth naming. There is something about working with wool — the smell, the texture, the way it behaves on the needles, the connection to a natural material with a long history in textile — that acrylic does not replicate. This is not a functional quality but an experiential one, and it matters to many knitters.
Stylecraft Special DK: the benchmark
Stylecraft Special DK has, over the past fifteen years, become the most widely used craft acrylic yarn in the UK. It is used in more online knitting and crochet communities, more shared patterns, more charity blanket drives, and more beginner knitting classes than any other single yarn. This ubiquity is not accidental — it reflects genuine quality at a genuinely accessible price point.
The yarn is 100% premium acrylic in a 100g ball with 295 metres — a generous yardage that goes a long way in most projects. It is described as premium acrylic for good reason: it is notably softer than standard acrylic, resists pilling well, maintains its colour through repeated washing, and has an even, consistent twist that makes it pleasant to work with. It is machine washable at 30°C, can be cool tumble dried, and can be cool ironed.
We stock 43 colourways at Craft and Canvas at £3.15 per 100g ball — a comprehensive palette running from clean neutrals (Black, White, Grey, Cream, Parchment) through a full spectrum of blues (French Navy, Midnight, Cloud Blue, Teal, Petrol, Denim, Storm Blue, North Sea, Mallard), greens (Spearmint, Meadow, Bottle, Mistletoe, Leaf, Apple, Lincoln), reds and pinks (Tomato, Matador, Pale Rose, Shrimp, Cinder Rose, Pink Rhubarb, Fuscia, Boysenberry), purples (Parma Violet, Purple Smoke), yellows and oranges (Lemon, Saffron, Mustard, Gingerbread, Dandelion, Gold, Citron), warm tones (Camel, Walnut, Spice, Vintage Peach, Sherbert), and brights (Fiesta, Buttermilk, Poppy). Something for every project and every palette.
The 4mm needle recommendation knits to 22 stitches and 30 rows per 10cm in stocking stitch — standard DK tension, which means it substitutes directly in any DK pattern without modification.
Stylecraft Special Chunky: the same quality, faster results
Stylecraft Special Chunky is the same premium acrylic construction as the DK but in a chunky weight — 100g per ball, machine washable, soft and consistent, suited to 6mm needles. At the chunky gauge it produces results considerably faster than the DK, which makes it particularly well suited to large projects where visible progress is motivating — blankets and throws, chunky accessories, quick gifts.
We stock 15 colourways at £3.15 per 100g ball: Matador, Midnight, Meadow, Silver, Storm Blue, and others. The colour range is smaller than the DK — as is standard for chunky weight yarn — but covers the most practical working shades.
For projects where speed matters and weight is appropriate — a chunky blanket, a quick hat, a cowl for a weekend — Special Chunky is the most efficient choice in our acrylic range.
Frequently asked questions about acrylic yarn
Is acrylic yarn safe for babies?
Yes — premium acrylic like Stylecraft Special is soft, non-allergenic, and machine washable at higher temperatures, making it in many ways more practical for baby items than wool. The machine washability is particularly important for baby garments that need to be washed frequently.
Does acrylic yarn pill?
Standard acrylic can pill, particularly in high-friction areas. Premium acrylic like Stylecraft Special is specifically formulated to resist pilling — it is one of the qualities that distinguishes it from cheaper alternatives. Good care (washing inside out, using a gentle cycle) further reduces pilling.
Can I use Stylecraft Special DK for colourwork?
Yes — it is one of the most popular yarns for colourwork blankets precisely because the extensive, consistent colour range and affordable price make it practical for projects requiring many colours in large quantities. The smooth, even twist also gives good stitch definition for colourwork patterns.
Is Stylecraft Special DK the same as Stylecraft Special Chunky?
They are the same premium acrylic construction in different weights — DK on 4mm needles and Chunky on 6mm needles. Both are 100g per ball at the same price. The choice between them is a question of the weight your project requires.
Can I substitute Stylecraft Special DK for wool in a pattern?
At the same gauge, yes — both knit to standard DK tension and the substitution works at the stitch level. The finished fabric will have different properties — less warmth, more washability, a slightly different handle. For garments where the drape and behaviour of the specific fibre matters, check whether the pattern calls for the characteristics of wool specifically.
Is it worth paying more for wool instead of acrylic?
For some projects, yes — for others, no. For a baby blanket, an amigurumi toy, or a gift for someone who machine washes everything, acrylic is the practical choice and spending more on wool is not an improvement. For a garment intended to provide real warmth, for a project where natural fibre quality matters to you, or for a piece you want to feel exceptional rather than simply functional, wool is worth the additional cost.
