Blog book by Blurb - print out blog posts into a book. Or scan your kids artwork onto your computer and print out the file and make a book at Walmart, CVS, or Walgreen's etc. Saw this idea on Oprah and it was excellent.
Family yearbooks. Since most people don't print out pictures like they used to, this would be a great way to document your years in pictures and still have hard-copies to look through/show people. What a cute idea!
