Why choose Merino wool? Merino sheep are world famous for having one of the highest quality fleece of any breed of sheep. The short and fine fibres used in Merino yarn create a luxurious and soft texture that has all the resilience needed to create long-lasting projects. At Woolyknit, we source our Merino wool from areas of the world where the process of mulesing isn't carried out. Click here to view our certifications.
