Regia makes fantastically hard-wearing sock yarn that washes brilliantly. One 100g ball will make a good sized pair of adult socks and all the different shades knit up with different effects. 75% wool and 25% polyamide, we can persnoally attest that this yarn makes the longest-lasting socks. The effects achieved when made into socks is illustrated on the ball bands, it's a great yarn for all sorts of projects but the effects will change if you don't make socks!
