This bulky weight self-striping yarn from Cascade is both beautiful, and soft. The compostition of the yarn is 46% wool, 35% acrylic, and 19% silk. The colors transition beautifully into one another, and really make your stitches sing. There's a generous 109 yards on each ball, which is plenty for a hat. If you're looking to make a scarf or cowl, you'll want to get 2 or 3. Handwash, dry flat. 3 - 3.5 stitches per inch on a size 10 - 11 needle. If you're crocheting, you'll want a 6 - 8mm hook.
