Have you made one? Does it work? Can you help me understand how it is supposed to work?
I have a hot water bottle made of real rubber. Even when I fill it with boiling water, it rarely gets so hot that I can't stand to have it next to my skin. And with lower back pain, this kind of heat is helpful. So what does a wool cozy do? Does it distribute the heat better? Hold the heat for longer? I'm trying to be sure it won't insulate so much that the heat I feel is minimized...
TIA, and of course, here's the pattern that I'm thinking of using...
