Topsy Farms 100% wool yarn is wonderful to work with. It is unbleached, washed only in natural soap, leaving it soft with natural lanolin and sturdy with unbroken fibres.
Fingering weight is 1-ply, worsted weight is 2-ply. All skeins weigh 4 oz - 1/4 lbs or 113 grams. Since most knitting stores sell yarn in 50 gram balls, be aware that you only need half the number of skeins called for in a pattern. Yardage varies per skein, but minimum amounts are 400 yards for fingering, 200 yards for worsted weight.
Topsy Farms yarn is ideal for sweaters, mitts, toques or socks, or for creative wall hangings and other pure wool projects. It also felts beautifully.
