This is what I get for surfing at work. This is silk yarn from Aurora Silk. Here's their description, "This yarn is good for knitting and crochet, and is a little heavier than the regular silk yarn. 4/2 N.m. aprox. 900 yds/lb. Skeins are 150 grams/5.4 oz, about 300 yds. Choose from 120 colors or natural (pictured)."
