Which yarn suits your project?
First, consider when and how you want to wear or use your finished piece:
- For warm winter clothing, virgin wool, merino, and alpaca are suitable.
- For light summer designs, cotton, linen, and viscose are a good choice.
- For a fluffy, airy look, you can opt for mohair.
- For sophisticated projects, silk or a yarn with a silk content is ideal.
- For heavily used or frequently washed items, robust blended yarns are particularly practical.
Also, pay attention to whether the yarn will be directly against the skin, how easy the finished piece should be to care for, and what yardage your pattern requires. A gauge swatch will show you how the yarn works up, whether you like the stitch definition, and how the material behaves after washing.
Ultimately, there isn't one best fiber – what matters is which yarn suits your project, your everyday life, and your personal comfort.
Plant-based wool, virgin wool, synthetics – these are the main pillars of wool types.
In the following, we explain the differences and the variations that exist.

Man-made fibers – easy-care and durable
Synthetic Yarns – Robust and Suitable for Everyday Use
Polyacrylic, polyester, and polyamide are manufactured industrially. These fibers are usually durable, dimensionally stable, and easy to wash – as pure yarns or blended with natural fibers. Polyamide makes sock yarn more resilient, while polyacrylic can add volume and reduce cost. However, synthetic fibers often absorb less moisture than natural fibers.
A look at the composition will tell you which fibers are contained in your yarn.
Well suited for: socks, everyday clothing, blankets, stuffed animals, and frequently washed knitted items Price: usually inexpensive
Viscose – Soft, Flowing, and Silky Sheen
Viscose is processed from natural cellulose – such as wood or bamboo – into fibers using a chemical process. The result is soft, smooth, drapes beautifully, and has a silky sheen. In yarn blends, viscose provides suppleness and a flowing appearance.
Since viscose can be more delicate when wet, you should handle the finished knitted item carefully and dry it flat, unless the care instructions recommend otherwise.
Well suited for: light tops, summer scarves, dresses, and softly draping designs
Price: inexpensive to mid-range
Plant Fibers – light and comfortable for warm days
Cotton – soft, uncomplicated and versatile
Cotton is skin-friendly, absorbent and easy to care for. It doesn't scratch, making it suitable for people who find animal fibers unpleasant. Since cotton retains less heat than virgin wool, it is ideal for lightweight garments and summer projects.
The material is less elastic – larger or heavier knitted items may sag slightly when worn. A gauge swatch will help you assess the yarn's behavior beforehand. The information on the ball band remains crucial.
Well suited for: summer tops, light sweaters, baby clothes, bags and home accessories
Price: inexpensive to medium-priced
Linen – cool, robust and full of character
Linen is obtained from the stalks of the flax plant. The fiber is stable, dimensionally stable and hardly pills. Because it can absorb and release moisture well, linen is comfortable to wear on warm days.
Linen yarn can feel firm or rough at first – it gets softer with every wear and wash. Since linen is hardly elastic, you should pay attention to even yarn tension.
Well suited for: summer tops, shirts, light sweaters and accessories
Price: medium-priced to high-priced
Animal fibers – warm, soft, and temperature-balancing
Virgin Wool – The Versatile Classic
Virgin wool comes directly from live sheep and is one of the most popular materials for warm knitted items. Its fibers trap air, providing good insulation against the cold. At the same time, wool can absorb moisture without immediately feeling wet.
Depending on its quality, virgin wool can feel a bit scratchy on sensitive skin. For sweaters you want to wear directly against your skin, a particularly fine quality or a soft yarn blend is worthwhile. Virgin wool requires some care when washing: too much heat and vigorous movement can cause the knitted item to shrink or felt. Therefore, always follow the care instructions on the yarn label.
Well suited for: Sweaters, jackets, hats, scarves, and warm accessories
Price: inexpensive to moderately priced
Merino Wool – Fine, Soft, and Comfortable on the Skin
Merino wool is obtained from Merino sheep. Its fibers are particularly fine and therefore usually feel softer than classic virgin wool – a good choice for garments worn directly against the skin.
Merino can retain heat while regulating moisture. This is why the fiber is also used for baby clothing, as well as sports and outdoor wear. Wash it gently and follow the instructions on the yarn label.
Well suited for: Sweaters, jackets, hats, scarves, and baby clothing
Price: moderately priced
Mohair – Feather-light and Fluffy
Mohair comes from the Angora goat and is known for its fine sheen and typical fluffy pile. It is often spun with other fibers to make the yarn more stable and easier to work with. It looks particularly beautiful in airy sweaters, shawls, and cardigans. Plan for some patience when unraveling; depending on the processing, small knots can form.
Well suited for: Light sweaters, cardigans, shawls, blankets, and decorative projects
Price: moderately priced to high-priced
Alpaca – Soft, Warming, and Durable
Alpaca fibers are soft, light, and exceptionally warm. Because alpaca contains very little lanolin, it can be of interest to people who are sensitive to classic sheep's wool – however, if you have a known allergy, you should still test it individually. Since the fibers are less elastic, heavy knitted items can lengthen; yarn blends often compensate for this.
Well suited for: Winter sweaters, jackets, scarves, hats, and particularly warm accessories
Price: high-priced
Silk – Elegant Sheen and Comfortable Feel
Silk feels soft and has an unmistakable sheen. In warm weather, it can feel pleasantly cool; in yarn blends, it provides smoothness and a high-quality look. Pure silk is costly and requires gentle care.
Well suited for: Fine tops, scarves, festive clothing, and elegant yarn blends
Price: high-priced
