Donegal Yarns Irish Heather yarn is a natural yarn from the Irish company Donegal Yarns. The yarn has a raw and rustic character. Its colors are delicately melange and multidimensional. It is a 3-ply yarn. Irish Heather yarn is a blend of 100% wool, including wool from New Zealand sheep. It is coated with spinning oil and at first contact may give the impression of string yarn. However, after washing and rinsing, it opens beautifully and becomes soft. Perfect for knitting warm autumn-winter clothes. It is a thin yarn, intended for knitting or crocheting, in size 3.0-3.5 mm.
