From Malabrigo:
 
Wearing an item made of Silkpaca is like wearing a cloud! This yarn is 70% baby alpaca and 30% silk, which makes it 100% luscious. Soft, silky, with just a bit of a halo. Despite being Malabrigo's thinnest yarn, it is plied and sturdy- perfect for lace projects and very special objects that are sure to become precious heirlooms.
