This has nothing to do with batting........but I was given a corn filled 13 x 16 filled sack that you heat in the microwave for 2 to 3 minutes.....what a blessing! The other night I couldn't get to sleep even though my electric blanket was up on 2. I heated that bag and put it at my feet [yes, I sleep with soxs on] and in a short time I was fast asleep! I've been doing that every night now before I go to bed and I sleep much better.
I'm making some for gifts with white rice filling instead of the corn as that is what I have.
