I have been working on a Heritage Album for some time now. I don't have any LO's posted yet, but here are some tips that might help.
When you go to the Gallery, Layouts, look under Themes--you will find Heirloom LO's. Or if you look under Styles---you can choose Heritage or Vintage. There is a lot of instiration there.
As for paper, embellishments, etc., I have bought a lot of stuff from K and Co (Ancestry Collection). Also, Graphic 45 makes some really nice vintage stuff, as well as Tim Holtz products.
