This link to the Hobbs website is a list of the different types of batting they manufacture. It's very useful when trying to decide what kind of batting to use.

I'm not affiliated with Hobbs in any way, but two of their customer reps visited our Guild a few months back and gave us a chard like this to use as a reference. I think Quilter's Dream has something similar on their website.
