These are all the yarns we currently have in stock that are wool-free; they are all made from blends of yarn that include non-animal fibers, like cotton, rayon, bamboo, acrylic, etc.  Wool-free yarns are becoming increasingly popular as machine-washable projects have become more popular, and as more people have developed allergies or sensitivities to wool.  Wool-free yarns are excellent for baby projects, housewares, and any other projects that will be in direct contact with sensitive skin, or that you'd prefer to be machine-washable.
