Joanns carry Insul-brite as does WalMart and most quilt stores.
I keep my batting scraps and use them in everything that have been discussed here. My one thing that hasn't been spoken of is STORING the batting in Space Saver bags that you suck all the air out of with the vacume cleaner. I put batting scraps of similar size in a bag and suck the air out. Doing this goes from a garbage bag sized bag to a small flat bag that takes up very little room but is easily available for use when needed. I put a piece of paper in the bag that says small, med. or large so I know which size bag to open when I'm needing a piece of batting. The Space Saver bags can be opened and closed a million times but you'll need to dig out the vacume to suck the air out after each opening. CAUTION: On the Space Saver bag it tells you where to STOP filling the bag...STOP! Don't overfill them as you'll tear the bag and won't be able to shrink wrap it once it's torn. How do I know this? Of course I didn't believe the caution when I saw it! :oops: :oops:
