Now there’s useful, and there’s USEFUL! And this pattern rocks. Keeps the hot water bottle hot and keeps it from burning your skin. Now, knit it up in some soft cotton and you’ve got a winner! But even better than that, this pattern is from Lion Brand, which means it’s Lola approved. And, even better than all that… it’s free! Here: http://www.lionbrand.com/patterns/90655AD.html?
