Aging paper opinions needed!?

I am putting togther a family cookbook with generations of recipes. I want the book to look as old as the recipes. I have already constructed the book cover(made to look like an old leather bound book) and I need to know about aging paper. Which is best & easiest for staining? Would I be able to run the stained paper through a printer? And how would I embellish the stained paper? (ie: gold speckle..) Thanks in advance for any help!!
