One of my co-workers asked me to knit her a hot water bottle cover. She's a librarian, a lawyer, a musician, and one of the nicest people you'll ever meet. So of course I made her one!
She picked the yarn, Muench Tessin (43% superwash wool, 35% acrylic, 22% cotton). It was fun to knit with, though bulky yarn is always very hard on my fingers. The end result is worth it, though. It's the
BAWK cabled hot water bottle cover.
