It's chilly in my house at night and I've been known to put on up to 5 quilts on my bed at once--on me.

I have used wool batting and a high quality flannel backing.

Wool would be the warmest I think. You might want to tie the quilt instead of "quilting" it.

If you can find a goose down comforter in the size you want it would be a very warm and light weight batting. In the past and over time I have purchased two of them at the local thrift store.

WOOL OR SILK……Hobbs makes wonderful wool batting that can be machine washed, and does not need to be densely quilted……I used their wool in the quilt I did for my Brother and SIL last year……they heat their entire 3 story Victorian house with the fireplace (no insert) in their living room - so bedrooms get cold……but they love their quilt and say they have a thin cotton blanket over the sheet and under the quilt, and need nothing else.

Buy her an electric mattress pad. My sister sent me one for Christmas and I love it!! Even DH likes it. We heat with wood and it's a blessing to crawl into a warmed bed. I will say I love the heavyness of blankets in the winter, so the more I have, the better I sleep. And yes I wear an oversized pair of socks as well to keep my feet warm for which hubby is thankful.

When it gets really cold (like camping in close to freezing temps) minky plus a comforter and sleeping in a fleece snuggly with fuzzy knee socks and a couple pairs of long johns works the best so far. 😌

I think the polyester is light and very warm, I have a throw size and ut that on top when I get cold and I am surprised how warm I stay.

Natural fibers are much warmer than synthetics, so I would go with either wool or silk.

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.
