Being a bit of a fiber snob, I wasn't sure what to think about a man made sock yarn. But, the second my hand connected with the ball of yarn, I fell in love with Berroco Comfort Sock yarn. First of all, it doesn't have that "acylic-y" feel you often get with man-made fibers. Comfort sock is light and soft with a wool type feel, but it's actually a super fine nylon & super fine acrylic blend. It's great for people with wool allergies and it's machine washable (always a plus for sock knitting). What I love most about this yarn are the color combinations. The colors are rich and stylish. I love the new Fair Isle prints in bright colors such as: Beach House, Cosmopolitan, and Fruit Cocktail.
Another plus about Berroco Comfort Sock yarn, the price! Comfort Sock is only $7.29/ball. At a generous yardage of 447 yards per ball, you'll only need one ball to make a pair of average size socks.
