I wouldn't use Warm & Natural if I could get it free. It's just too stiff if you do very much quilting. I like Hobbs heirloom 80/20 for most quilts and Quilter's Dream poly for kids quilts and wall hangings. I buy Hobbs by the case from Hancocks of Paducah. I have a roll of Dream Poly I'm still working on using up and when it's gone I may consider another roll.
