Two shades of blue merino carefully blended with my undyed merino/silk fiber make up Day sky, my depiction of the skies near where I live on a clear day! This batt is 100% hand blended by me on my blending board. Each of my batts are made with love and lots of arm muscles! It has Merino, Sari silk, Firestar and a sprinkling of Angelina. This batt weighs 1.1 ounces.
