Its an acryic yarn from Caron.
EDIT: I found out how to block acrylic yarn!! Since its essentially plastic, you need to steam it to get it to block out evenly as described in this knitter's blog entry: http://beadknitter.blogspot.com/2009...k-acrylic.html
I have a steam iron, and just need to figure out where the blocking board went. Oh, I'll figure that out when I finish the scarf.
