Description from Knitty.com:

“Sally, the Eco fairy, was designed for the discriminating young person. Made from undyed, organic Ecoknit cotton, she is hard-wearing, washable, and totally non-toxic. Or you can use up your leftovers in the yarn of your choosing and she will be just as cute--but not quite so eco-friendly. Even her removable dress and panties are designed to be totally baby safe.
The DK-weight yarn is knit at a much tighter gauge than recommended on the ball band. Knitting Sally very tightly will keep the stuffing from showing through, and will give the toy a longer life.”
