Oh my oh my oh my! I need one of these so badly!
I've never heard of them or even thought about something like this. I have the grumpiest tummy EVER! As soon as it's just a little bit cold, I get a stomach ache. It feels as though my stomach contracts and it hurts a lot.
I've considered wearing one of those heat patches that heat up when you open it and you stick it onto your stomach (or hands, they make them for mountain climbers too), but they are very expensive, even if they last up to 8 hours.
This is ideal! I love it, it looks pretty too, especially in this pic:
I'm going to knit up some and sew some in pretty fabric, for good measure. It's Spring now, but come next Winter, I'm going to be ROCKING these belly warmers! Thanks so much for introducing me to it
