Which wool for which season? A guide for winter and spring
Share
If you've ever knitted or crocheted with the wrong yarn, perhaps because it was too warm, too scratchy, or simply too heavy, then you know how crucial the choice of the right material can be. Unfortunately, wool is not just wool. Every fiber has its own unique strengths, and especially when knitting for different seasons, the right choice can determine the comfort, durability, and even the appearance of your project.
So, let me start by explaining why it's so important to use different types of wool for different seasons.
Why the right wool is crucial for every season
Wool is a natural wonder. It can warm you when it's cold, cool you when it's warm – and it's incredibly versatile in its texture. Nevertheless, there are big differences between alpaca, virgin wool, merino, cotton, and blended yarns. These differences affect:
- Thermal performance
- Breathability
- Moisture regulation
- Weight
- Wearing comfort
- Care requirements
A winter sweater made of cotton? Sounds like a good plan – but it's not. Cotton hardly stores any warmth and becomes heavy when it absorbs moisture. A spring cardigan made of pure, dense alpaca wool? Beautiful, but probably far too warm. Below is a comprehensive guide for winter and spring, so you never choose the wrong wool again.
Which wool for winter? – The best yarns for the cold season
In winter, it's all about warmth, coziness, and temperature stability. We need fibers that insulate while remaining breathable. This prevents you from getting too warm indoors or too cold outdoors – a balancing act that natural wool has perfected.
Why winter wool needs special properties
When temperatures drop, you need fibers that:
- Store air in their hollow spaces (thermal insulation)
- Absorb moisture without feeling wet
- Have a temperature-regulating effect
- Remain light, even if they look voluminous
The ideal winter wool keeps you warm but doesn't make you sweat.
Merino wool in winter – the all-rounder for warm and cold weather
Merino wool is probably the most versatile fiber for cold months. Why?
- It is soft, which makes it perfect for next-to-skin wear.
- It is breathable, so you don't sweat in a warm living room.
- It is warming, but not heavy.
- It still feels pleasantly warm even when damp.
Perfect for:
Sweaters, scarves, hats, cowl neck scarves, baby knitwear.

Our extensive selection of merino yarns will get you through the winter well.
Alpaca wool – the queen of winter yarns
Alpaca fibers are naturally hollow. This means:
- They store more warmth than sheep's wool.
- They are also lighter.
- They are often hypoallergenic because they contain no wool grease (lanolin).

For people who get cold easily, alpaca is therefore a dream. We recommend our Baby Alpaca Wool.
Which wool for spring? – Light, breathable yarns for milder weather
Spring is known to be changeable: warm during the day, cool in the evening, sometimes suddenly damp, then sunny again. For this transitional period, you need yarns that are not too warm, but also not too cool.
This is when lighter natural fibers come into play.
Why spring wool needs different properties
The best spring yarns are:
- Breathable, so you don't overheat
- Lightweight, for airy patterns
- Temperature-regulating
- Easy to care for, as spring items are often everyday wear
Merino wool in spring – yes, really!
Merino can do much more than just keep you warm. Its ability to regulate temperature also makes it ideal for spring days.
Advantages:
- Warms in the wind, cools in the sunshine
- Is super soft on the skin
- Perfect for lace patterns or thin sweaters

Cotton in spring – breathable and perfect for knitting & crocheting
When it gets warmer, cotton yarns and cotton blends are unbeatable. The advantages of cotton at a glance:
- It is skin-friendly
- It is durable and machine washable
- It is ideal for crocheting and airy knitting projects
- It absorbs moisture, which is very pleasant in spring
Perfect for:
Spring sweaters, tops, baby knitwear, summer cardigans.
