I have been using warm & natural from Joann Fab by the bolt for many years.....it will usually last a year or so.....I would recommend it highly. I have made, used, washed bed quilts now well over 10 yrs old and they are as good as new.......BUT the other day I was there waiting to pick up my bolt and saw some other "cotton batting"....forgot who the maker was, but I would never purchase it.....it was flimsy, attached..almost..to some sort of netting...in my opinion a poor excuse for batting.....although the price of w/n has gone up, like the cotton fab has, I feel their quality has remain superb
