Wool is the raw material, a fiber from sheep and some other animals, while yarn is the finished, loosely spun thread for knitting that can be made from wool, cotton, acrylic, or blends. Thus, any woolen knitting thread is yarn, but not all yarn is wool. The confusion arises because in everyday speech, the word "wool" is used to refer to any ball of yarn.
To sum it up
- Wool - is a type of fiber (raw material) of animal origin, yarn — this is the form of the product — yarn for knitting and crocheting.
- The yarn can be wool, cotton, acrylic, linen or a blend – the composition is always indicated on the label.
- Wool is warm, water-resistant, and can be felted; synthetic yarn is cheaper and easier to wash, but less breathable.
- The word "wool" also refers to yarn and products made from animal hair, hence the common confusion between the two.
Yarn – Definition and What It Really Is
According to the PWN dictionary of the Polish language, yarn is «"a loosely twisted woolen thread used, for example, for hand knitting.". The dictionary definition points to the traditional woolen origin of the word, but in the knitting industry and practice, yarn is now understood to mean any yarn intended for knitting: with needles, crochet hooks, or on a loom.
The yarn differs from ordinary sewing threads primarily with its thickness and softness . It is fluffy, sold in skeins or balls, and the manufacturer's label indicates the composition, the length of the yarn per unit weight (for example, meters per 100 g), and the recommended knitting needle or hook size.
What is wool?
The PWN dictionary gives two main meanings for the word "wool": wool of sheep, camels, goats and some other animals , as well as the yarn obtained from this wool (and the products made from this yarn). This is why we call a ball of wool yarn simply "wool.".
However, in trade, more specific rules apply. Regulation (EU) No. 1007/2011 on the designations of textile fibres defines wool as fibre from sheep or lambskin, possibly mixed with wool from animals specified in the regulation (e.g. alpaca, llama, camel, cashmere goat, or angora goat). The designation « virgin "wool" can only be used for wool that has not previously been used in a finished product.
The most popular types of wool in yarn
- Fleece – the most common, warm and elastic; merino The wool has a thin, soft fiber, less prickly.
- Alpaca – very warm and light, made of alpaca wool.
- Mohair – the wool of the Angora goat, fluffy and shiny.
- Angora – made from Angora rabbit wool, which is exceptionally soft and fluffy.
- Cashmere - this is the undercoat of the cashmere goat, soft and expensive.
Wool and yarn are the most important differences.
Simply put, Wool answers the question "what is it made of?" and yarn answers the question "what is it?"« . Wool is a material that can be made into yarn, as well as coat fabric, felt, blanket filling, and carpets. Yarn is a specific product—a knitting thread—that can be made from a variety of different raw materials.
You can find yarn in sewing supply stores. made of wool (100% wool), cotton , flax , acrylic и mixtures , such as wool with acrylic or polyamide. Blends combine the benefits of several fibers: the addition of synthetic fibers increases durability and reduces cost, while wool provides warmth.

Properties of wool and synthetic yarns
Woolen yarn It's warm, elastic, and holds its shape well. Wool can absorb a significant amount of moisture before becoming noticeably wet, making wool sweaters, hats, and socks ideal for winter and mountain wear. Its downside is its tendency to stalling – Warm water, detergent, and friction cause the fibers to intertwine, causing the fabric to shrink. Wool labeled « superstir"» is treated to reduce this tendency.
Acrylic yarn It's cheaper, lighter, doesn't itch, and is generally machine washable. However, it's less breathable, can accumulate static electricity, and can form pilling over time. Cotton Cool, airy and hypoallergenic, but less elastic – perfect for summer blouses, toys and children's clothing.
Which yarn to choose? Practical advice.
- Read the label carefully. The word "wool" in a product name does not guarantee its composition - what is important is the percentage of fibers indicated on the label.
- For warm winter clothing Choose yarns with a high wool content, such as merino or alpaca.
- Socks – wool and polyamide blends are well suited, as they are more wear-resistant.
- For children and people with allergies , it is recommended to use cotton, soft merino wool, or acrylic intended for babies; sheep's wool can scratch sensitive skin.
- Wet and dry felting - Unprotected wool that is not labeled as "superwash" is required.
- To start learning – a smooth, light, medium-weight yarn makes counting stitches easier; fluffy mohair is best left for later.
- Choose knitting needles according to the manufacturer's recommendations and make a test sample before tackling a larger project.
