I find wool and most all animal fibers (yes even cashmere, tragic) too itchy to wear. As a result I’ve missed out on a lot of cozy sweater wearing in the past. Happily manmade fibers seem to have caught up and these days I’m finding more and more acrylic/cotton blends that are soft and fuzzy and, most importantly, warm. My most recent find is this wrap cardigan from Old Navy. I might buy two.
