Lots of reasons. It's incredible drape, it's lovely lustre - light and airy - its anti-bacterial properties make it great for babies, and it's moisture - wicking tendency makes it a great all-year fabric. ESPECIALLY if you have animal-fiber sensitivities - this yarn makes perfect sense as an alternative to wool. This 5 ply stunner is hand dyed by a master, and every skein is a generous 400 yards! This is a fingering weight yarn. and would work well for a tank, or an openwork shawl.
