I haven't tried it yet, but I do have a some of their classic wool, in my stash.
When I saw the post I remembered I that I got some of their yarn as samples from one of my editors at work. I also got the Art of Knitting DVDs (both 1 & 2), they were included in the press pack she received. Since we don't cover fiber arts, she gave them to me!! I do have samples of their Bell Dk, Cassie, Opal, Bellagio, Twister and Coral. They are little balls of yarn though, don't know what I would do with them.
