My favorite is anything from Warm and Natural, it is sturdy but still easy to hand quilt through. I enjoyed working with Hobbs Heirloom fusible - but it is 20% polyester and I don't care for that, but I will use it for wall hangings and table items. My second favorite is Soft Touch 100% cotton, quilts up really nice and drapes lovely, I just don't care how if I tug on it ...it rips too easily.
Not about batting, but I used a Pellon fusible interfacing yesterday and loved it!
Your name sounds/looks familiar...have you judged quilt shows?
