My memorabilia used to be stored in containers like this:
While I scrap primarily in chronological order (with Project Life) I also scrapbook out of order and grab my old memorabilia (letters, movie stubs, paper clippings, old photographs, etc,) to scrapbook memories from the past or to do a comparison/contrast. Now, my memorabilia lives in a binder and the good thing about that, it is easier to flip through everything and it is portable, so when I scrapbook at a crop I can grab my binder and take most of my memorabilia (to be scrapbooked) with me.
In order to create your binder all you need is a binder, and some clear 8 1/2 x 11 sheet/page protectors. I buy my page protectors in bulk from the Office Supply Store and 200 come in a pack. Here are some of the things you’ll find in my memorabilia binder:
The photo above features Monopoly property cards from an old Monopoly game. I’m planning to make two layouts about my family’s love of playing Monopoly and will incorporate these property cards (which have special significance).
Hard copies of some of my husband’s old music from his teen days & beyond.
These are handwritten letters to God that I used to keep in something called a God Box (read more about the God Box Prayer technique here: http://www.realsimple.com/work-life/family/relationships/inside-god-box-00000000045743/index.html
These are old airline tickets.
In some of the page protectors you will also find an index card. I buy oversized index cards and write stories/notes for the actual layout whenever I get around to writing it, that way I won’t forget why I saved the piece of memorabilia in the first place.
