Have you heard of vegan wool? It is about the Dralón. This dry-spun fiber has a lot of properties such as great resistance and softness, hypoallergenic, ideal for making garments for babies or sensitive skin
It comes in two formats, 250gr/250m or 1000gr/1000m.
If you are going to make a sweater, I recommend the 1kg format and surely you will have a little left over. You can work it with knitting needles or granchet hooks between 5/7 mm
