Altering books can be a great adventure. There are no rules, no rights and wrongs. There are infinite ways to use all your favorite art supplies and skills to alter an old book. I hope you visit often. Please feel free to use any ideas and tricks you pick up here. I do this for fun, not for profit! One of my best tricks is - if you mess up a page, tear it out! Start a new page. That's "my way".
I recently added the mail art component here. What could be easier or more fun than making a post card and sending it off to a friend? Or to a stranger?
Here is a scan of a Christmas Card my dad sent to his dad from Alaska in 1923. I believe it is printed directly on a piece of thin bark which has been pressed flat. Maybe my brother can use it in the video he is preparing on Alaska using photos from Dad's time and also from his trip there.
