Sarafina Carob Core We are happy to offer our favorite core in a graphite gray. Made with springy, consistent, short fibers, our core is the best we have found for needle felting. Whether building large shapes with a full width of roving or working in small details, this roving gives you great control and ease of felting. It's a perfect core wool but don't let that limit you, you will love the colors for accents and marking as well. Carob is a dark gray balanced between warm and cool. 2 oz bundle
