What happens when mistakes are made in a mill like Brown Sheep Company? It quite often becomes a happy outcome. That is exactly how Serendipity Tweed came a to be, a mistake became a wonderful new line of yarn that we thought was too good to keep to ourselves. At 60% pima cotton and 40% wool, this great new yarn has a fresh look, an excellent handle, and a growing line up of colors (32 currently). The knitting gauge is almost exactly like Cotton Fleece so any pattern that is designed for Cotton Fleece can be used for Serendipity Tweed. We hope you enjoy our happy accident.
