I am about to put together an all batik (100% cotton) queen size top with a close weave 100% cotton backing ( much heavier then the top) for my son and wife called Circle dance. I have read many articles on batting and I am no wiser. However, with all my reading I have discovered that to make it cozy I need heIp. What would be the best batting for a floppy/flexable quilt that would be all season? Not to hot just warm. I guess I mean breathable. My son does not want it heavy either. Should I consider changing the backing?
