“These suri alpaca marl yarns are 4-ply 2/9Nm, 50g skein, 225m approx and we suggest using 3mm needles 28stsx36rows.
They are made with two contrasting 100% SF suri natural yarns twisted together & are available in six varieties, spun fully worsted at a small mill in Dorset.
There are two alpaca fleece types, huacaya and suri. Huacaya, a crimpy fleece, is the most common. The suri has a long fleece with non crimped locks and is known for its lustre and drape and accounts for only 5% of the world’s alpaca population. It is more difficult to spin because of its very low scale height but that gives it its lustre..
All of the suri fleece comes from alpacas farmed in Britain and was hand graded at our farm in Devon.”
