Knitting for Olive Heavy Merino is a perfect yarn for indoor wear on cold days, and for outdoor wear on warmer days. This worsted weight, bouncy merino is a heavier version of the Knitting for Olive Merino fingering weight we have been carrying for a few months now. Knitting for Olive is a family run business based in Copenhagen. Their colour palette includes some lovely ocher and petroleum blues and they design their own patterns to coordinate with their yarns. This yarn is produced in Italy, following ethical, technical and environmental standards in order to create a yarn free from harmful chemicals.
