Hi everyone. I need some advise. I made this bag for electronic gadgets and I used quilting batting for the padding. I sewed the batting to the lining and zipper but when I turned it inside out all the batting some how bunched up and ended up on one side of the bag. I've sewed with batting before on other bags with no problem but this one doesn't want to work. Should I use Pellon fleece instead or is there something else I can be using? Thanks for any advise.
