Prima is a lovely yarn made using 80% Bamboo, blended with merino wool. It has a lovely drape and sheen, similar to the cathay yarn and can be knitted in place of cathay as the tension is the same.
It knits as a Dk with 22sts and 30 rows to 10cm, on a 4mm needle. It is machine washable on a 30oC wash. (100m per 50g)
