Donegal Yarns Soft Donegal yarn is a natural yarn from the Irish company Donegal Yarns. It is characterized by colorful flecks on threads in the base color. It is a 1-ply yarn. Soft Donegal yarn consists of 100% natural merino wool. 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 medium-weight yarn intended for knitting or crocheting in a size of 3.5-4.0 mm.
