I use Craft-bond and/or Decor-bond for my purses. The Decor-bond makes a stiffer purse. I also use the fusible fleece in some of my bags. The Heat and Bond is for joining two pieces of fabric together back to back. That will work if you want to fuse the lining to the outside of the bag. Woven interfacing is just what it says, it looks like a regular piece of fabric but has fusible on one side. The non-woven interfacing has no grain.
