Scrapbooking is something I've always loved as not only a hobby, but also as a way of preserving our family memories and history.
One of the things that really spurred me on was to be left an album of my Great-Grandmother's that (sadly) has absolutely no journaling in it, so now I have no idea who the other people are, where they were at, what the event was, etc. Anyone who might have remembered has passed away. Someday, soon, I will post a pic of this album.
The question I always ask is "Where are your photos"? If they are in old magnetic albums, or in a shoe box somewhere, I would encourage you to buy a cheap photo save pencil and storage boxes and (at the very least) sort, label and safely store the photos for the future.
I always thought I'd remember our picture details, but I sometimes don't and have had to have help recalling everything! You don't have to be into scrapbooking at all, just document the information for the future. Your kids and grandkids will appreciate it, I promise! Still, should you become enamoured with scrapbooking any time soon, I'd be happy to help you get going!
