This sockyarn can endure quite a bit! Robust, but pleasently soft it is the ideal yarn for socks you'll be able to wear and enjoy for years. They can be machine washed without any worry (cold, delicate cycle) and have a great by long-term performance. Of course this yarn is also great for long-living cardigans, shawls and so on - but I recommend: socks, socks, socks!
