Got this to ply with a Suri alpaca fleece that I processed and spun. The merino spun so incredibly thin (which is exactly what I wanted) that about 3/4 of a lb filled my Ashford Kiwi 3 bobbin to the brim. So far I have spun & plied about 700 yards, and still have over half a bobbin left to ply with. The merino is so soft, and plied with the alpaca, it created incredibly soft yarn!
