There are four choices of fingering weight yarns to choose from at Knit Picks. Betsy's scarf knits up beautifully in both tonal or solid colors. The Royal Vines Scarf photographed is knit in Stroll Tonal Sock Yarn. One 100 gram skein makes a generous size scarf.
Be sure to check out Betsy's website Cultured Purl for more of her knitting designs.
