I have recently discovered wool batting and love it, particularly for larger quilts because of the loft, suppleness, and drape. Bamboo/cotton is nice but had a bit of a problem with bearding in loosely woven fabric, would work great in batiks. Cut my teeth on Warm & Natural and Warm & White and will continue to use it but not my first choice any longer. Bought a roll of Dream Wool from LQS for $10/yard which I considered pretty reasonable, that was last year. Like Hobbs wool products, also. Lots to consider!
