I've used Warm and Natural (W&N) 100% cotton for the last 15 years. Tried poly and found it to be too slippery so haven't used it since. I just did a quilt with Hobbs Wool and absolutely love it - It is a twin size used as a throw for my husband. It is much lighter than the W&N, very warm and when I completed the quilt I washed it in a large capacity washer and dried it in a large capacity dyer on medium. It dried quicker than the W&N quilts do. Not the crinkle look you get with W&N but looks great and my husband loves it again it is much lighter then the W&N so still warm and without the weight. I will definitely use Wool in the future but not for everything as it is higher than the W&N. I purchase W&N on a roll and the Wool on a roll is more expensive so will use up my W&N and consider wool next time I purchase a roll.
