I use a lot of Warm & Natural and like it a lot. My favorite is the bamboo blend they sell at Hancocks- will watch batting sales like a hawk and buy as much as I can when the price is good. I don't know what the brand is, but it has such a nice drape. I also use the Hobbs 80/20 - like that I can get that in black - and the Hobbs Wool - Also like both of them, but have to keep in mind the minimal quilting distance. I think of the wool as a luxury batting and only use it on special quilts. I see that Connecting Threads now has a bamboo blend, so as soon as they have a batting sale I will be buying that one for sure. I don't use 100% poly batting because it's like nails on a chalkboard for me - can't stand to touch it.
