faux hot water bottles - next short-attention-span project

i saw this amazing flannel "owie" fabric at stonemountain yesterday, but just as i was leaving, so i didn't grab any - it was living among the many types of sock monkey designs.

i want to make my mom's hot/cold rice pack in the shape of a hot water bottle and make a cover in this fabric. but i am not the first!

there was also a coordinating banana fabric that would be awesome for a babybib.
