Types of Knitting Wool
A Fashion Guide to the Fibres Behind Beautiful Knitwear
Introduction
A beautiful knitted sweater begins long before the first stitch. It begins with the fibre.
Walk into a yarn shop and the names can seem endless: Merino, cashmere, alpaca, mohair, lambswool, Angora and Shetland. They are not interchangeable. Each fibre has its own combination of softness, warmth, elasticity, texture, drape and durability—and those characteristics influence the finished garment.
Strictly speaking, not all of these fibres are technically wool. Wool traditionally refers to sheep fibre, while cashmere comes from goats, mohair from Angora goats, alpaca from alpacas and Angora from rabbits. In everyday fashion and knitting language, however, they are often discussed together as luxury animal fibres for knitwear. (Heddels)
Merino Wool
Merino wool comes from Merino sheep and is one of the most popular fine wools used in contemporary knitwear.
Its fine fibres give it a considerably softer feel than many traditional sheep wools. Merino also combines warmth, elasticity and breathability, making it useful for everything from lightweight sweaters and cardigans to socks and base layers. (Sullivans International)
Fashion character: soft, refined, versatile and comfortable.
Lambswool
Lambswool is obtained from a young sheep's first shearing. The relatively fine, soft fibres make it particularly attractive for comfortable knitwear. (Heddels)
It is commonly used for sweaters, scarves, cardigans, blankets and other cozy pieces.
Fashion character: soft, warm and traditionally woolly, without the heavier feel of some coarse wools.
Cashmere
Cashmere is one of the most celebrated fibres in luxury knitwear. It comes from the fine undercoat of cashmere goats rather than sheep.
The fibre is exceptionally fine, lightweight and insulating, producing the characteristic softness associated with cashmere sweaters, scarves and cardigans. Its limited fibre yield and delicate nature contribute to its premium position in fashion. (Wisconsin 4-H)
Fashion character: exceptionally soft, lightweight and luxurious.
Alpaca
Alpaca fibre comes from alpacas, camelids native to South America. It is known for softness, warmth and a naturally lustrous appearance.
Compared with traditional wool, alpaca can produce knitwear with a particularly soft, fluid and luxurious drape. It is used for sweaters, scarves, coats and other cold-weather pieces. (Wisconsin 4-H)
Fashion character: warm, soft, fluid and slightly lustrous.
Mohair
Mohair comes from the Angora goat, not the Angora rabbit.
Its longer fibres create the distinctive fuzzy halo that makes mohair so recognizable. It can be lightweight while providing considerable warmth, and its slight sheen gives knitted garments an almost luminous appearance. (Wisconsin 4-H)
Mohair is particularly beautiful when used in soft oversized sweaters, scarves, cardigans and delicate layered knitwear.
Fashion character: airy, fuzzy, luminous and romantic.
Angora
Angora comes from the fibre of the Angora rabbit. It is exceptionally soft, light and fluffy.
Its delicate fibres create a characteristic fuzzy appearance, making it particularly suited to luxurious-looking knitwear. Because of its characteristics, Angora is frequently blended with other fibres in yarns designed for knitting. (Wisconsin 4-H)
Fashion character: feather-light, fluffy and exceptionally soft.
Shetland Wool
Shetland wool comes from the Shetland sheep of the Shetland Islands.
It has a distinctive rustic character and is traditionally associated with durable, textured knitwear. Compared with very fine Merino, Shetland can feel more substantial and woolly.
It is particularly suited to traditional sweaters, Fair Isle-inspired designs, cardigans and textured knitting.
Fashion character: rustic, durable, textured and heritage-inspired.
Corriedale Wool
Corriedale is a sheep's wool developed from British longwool and Merino ancestry. It is valued for its combination of softness, strength and useful elasticity.
For knitters, it can be a practical choice when a yarn needs to balance comfort with durability.
Fashion character: resilient, versatile and comfortably woolly.
Wool Blends
Some of the most interesting knitting yarns are blends.
A yarn may combine Merino with cashmere, wool with alpaca, or wool with mohair. The purpose is not merely decorative: combining fibres can alter softness, elasticity, warmth, drape, strength and cost. (Wiley Catalog Images)
For example, adding alpaca or cashmere to wool can create a softer hand, while other fibres can be incorporated to improve durability or shape retention.
This is where yarn design becomes particularly fascinating: the final character of the knit is determined not only by the individual fibres, but by how they are combined and spun.
The Yarn Weight Matters, Too
There is another distinction worth knowing: fibre type and yarn weight are not the same thing.
Merino, for example, can be spun into a very fine yarn for delicate garments or a much thicker yarn for a substantial sweater. The same is true of alpaca, wool and many blended fibres.
Yarn weight therefore influences the scale, density and visual character of the knitting, while fibre influences qualities such as softness, warmth, elasticity and drape. Knitting references commonly classify yarns by both fibre and weight because both affect the finished fabric. (Martha Stewart)
Choosing the Wool for the Garment
The choice of yarn should ultimately follow the garment you want to create.
A fine Merino may be beautiful for a fitted sweater. Cashmere lends itself naturally to luxurious lightweight pieces. Alpaca can create warmth with a softer, more fluid appearance. Mohair introduces a distinctive fuzzy halo, while Shetland brings traditional texture and character.
And sometimes the most beautiful result comes from a blend.
The beauty of knitting is that the fibre becomes part of the design.
You don't simply choose a colour. You choose texture, warmth, movement, softness and personality—one strand at a time.
