I am almost finished with the top of the rag baby quilt BUT concerned about using filling that might be too hot for infant. Top is flannel and have read where using too much flannel fabric in quilt makes them very warm. Since this is a newborn I don't want him sweating or too warm. What do think? Quilt batting?Warm n Natural? The backing will be cotton nursery print fabric. I know, I know....but it is my first one....and need to use up my stash...
