I used the Hobbs 80/20 and I never had any problems with bearding. I love to hand quilt it and the drape is very soft. I also used 100% cotton several times and the brands I used quilted a little bit harder than the 80/20 - but I love the antique look after washing. I agree with Pam - fold marks come out easier with polyester, but I still prefer the cotton or cotton blends. For me Warm & Natural and Mountain Mist is not available here in Germany - but if I find it one day of course will give it try.
