I've been using Red Heart yarn for years and it's always been nice and soft and easy to work with.  However when I chose this variegated combination to use in my current project I noticed it's very scratchy and rough feeling and also hard to work with.  It doesn't slide off the crochet hook easily.  I love the colors they make in this combination yarn but there is something about the fabric content that makes it scratchy so I won't be using it again.  I compared the content to the plain colors and it's the same so they must be doing something in the color process that makes it rough.  Come on Red Heart I know you can do better, your yarn has always been so great to work with and such a bargain to buy.  Don't mess it up now!  I'll stick with the solids.
