I make quilts that are meant to be slept or cuddled under, so I tend to use all cotton in thread, fabric, and batting. My favorite thread is Aurifil 40 wt., and my favorite batting is Quilters Dream Select (I think that's the one with the pink label). I do use Warm and Natural occasionally, but I find Quilters Dream has a softer "hand." I have used wool batting for some smaller art pieces and wall hangings. I never use polyester batting anymore because I find it creeps through the fabric after a while (this is called "bearding"). Welcome to the world of quilting!
