My mother backed several quilts with Thinsulate or fleece. I LOVED them. I think she used a very lightweight batting. I do know those were warm and cozy quilts. I don't think she cared for them because she always liked a pattern fabric for the back like cotton.

No one mentioned hand quilting...guess machine quilting is assumed. But I would not double the batting if you plan to hand quilt it, unless you don't mind having larger stitches.

I think the question of whether a quilt is too warm or not depends upon the temperature of your room at night. Some of us keep central heat turned up very high in winter and some of us have space heaters which do not heat a room as warm. Only you can determine what will be warm enough or too warm for you personally.

well, this quilt will be a throw for my daughter who lives in CT. I made one for her last year with cotton batt and she says it is not warm enough in the winter... they keep their house just above freezing, I think! LOL

I just went to my LQS and told them I wanted to free motion a quilt that had a cotton top, then warm and natural, then Dream wool and a flannel back because my daughter is very cold. The owner of the shop is very cold natured and said she has a quilt with just wool batting and cotton top/bottom and is warm and cozy. I came home and took the w/n batting out and will free motion quilt today. Wish me luck!!!!

Ione, maybe you would like to consider making the top from wool instead of cotton. That makes the warmest quilts of all.

Wool batting is the way to go. I sleep with just a wool quilt and stay plenty warm and that's with the heat turned off in Oregon in December. My other quilts, I'd freeze to death.

Any clothing I put on that has any % of wool in it make me itch immediately. I would be afraid to use a wool batting for that reason. Does anyone have any experience with that scenario?

I made a wool batt quilt for my son who is wool sensitive. He's using it and loving it. Interestingly, most people who are sensitive to wool are also lactose, or milk, intolerant. Important to know for kids quilts especially. But since my son is both, i guess it's not so important to know after all. Lol.

Thanks to everyone who gave such good advice. I think that now I will make a lot of warm quilts. Using the many ideas you gave me! You can always depend on this board for help, isn't that great?!
