I had intended to order Nature Spun Sport from Brown Sheep, so imagine my surprise and disappointment when I received a box of worsted.  Although Brown Sheep was willing to send a call tag, I decided to think about it.  After holding a skein in my hand, I realized I had just solved one of my inventory dilemmas.  I needed a  worsted weight equivalent to Cascade 220 or Plymouth Galway (both from Peru), but I wanted a USA yarn and here it was!   Problem solved.
