Frog Tree Sportweight Alpaca is a great choice for a lightweight yet warm garment. It is so soft, and it's available in a wide range of colors. Frog Tree Alpaca Yarn is produced by a non-profit cooperative in Peru. At the cooperative they start with the raw alpaca fibers and go through the entire process of sorting the fibers according to color, cleaning, spinning and dyeing the yarn. Purchases made by T & C Imports provide support to this cooperative, and allows the cooperative to provide work to a number of women to supplement their household income.=
