About the fibers: 18.5 micron Merino wool combed top. This base is one of my favorites. It is extremely soft yet has a little body. It’s easy to spin, having just enough tooth to not slip through your fingers, and the staple length is just right. It’s also a favorite of wet and nuno felters. Polwarth wool combed top. This batch is SUPER soft, my supplier says 21-24 microns, it’s definitely down towards 21 microns. So yummy!! A lovely spin, skin friendly and easy drafting. Sold in 4 oz increments. Dye to order, 2-5 days fulfillment time. Expect minor variations between braids. Mirrored gradient (MG) color layout. Last photo shows the mirrored gradient and shorter, repeating colors (SC) versions side by side. The SC version is available in a separate listing. Currently pictured on the Polwarth base.
