Beautifully heathery Border Leicester and bast bamboo roving with a little BFL lambswool to add blacks to the mix. Wool is approximately 75%, bamboo 25%. This listing is 4 ounces. Bast bamboo differs from what is usually seen in commercial products. Most bamboo spinning fiber is a manufactured fiber produced by ejection of a thin stream of a solution of chopped bamboo. It is generally fairly slippery to spin alone and has a very silky feel. Bast bamboo is obtained from retted stems of bamboo similar to flax. It is a naturally occurring fiber, less slippery and has more "tooth" when you spin. As a cellulose fiber, it will take up acid fast dyes poorly if you decide to dye this fiber. The last photo shows a sample yarn. Staple length is mostly 4 inches or longer except the BFL lamb. This fiber spins smoothly and drafts easily. It is not scratchy although I do not recommend it as next to skin soft. The drape and strength is excellent. Think weaving. This fiber also Felts quickly showing nice luster.
