I'm finally becoming a convert to the Project Life kind of scrapbooking, although you won't find me committing to doing a two-page weekly spread. I think this kind of approach can work well mixed in with traditional scrapbook pages. Especially since I realized I spent the majority of my time last year putting together mini albums instead of scrapbook pages.
In the fall I started collecting Project Life items -- tons of different page protectors, lots of 3x4 cards, and a WeRMemory Keeper 3x4 punch. I'll admit part of the appeal to this is all the cute 3x4 cards that are out there. After compiling quite a stash of materials I did ... nothing.
So, I spent some time in December and went through this huge pile of things I'd been saving - ticket stubs, pictures my kids drew for me, programs -- all sorts of everyday ephemera that I wanted to save. I then divided it into piles by date and used empty 8.5 x 11 page protectors to temporarily store my piles in the appropriate album by year. I keep all my pages in chronological albums, but I used D-ring binders as I scrap all over the place. D-rings let you move things around and add new pages easily.
The next step was to place these items into Project Life protectors in the correct chronological spot in my album. Here's a couple notes I got from volunteering on a field trip, and you can see programs inserted into page protectors peeking out from behind.
And another where I've got ticket stubs from two events in the same time. My next step is to look through the photos I've taken during that day, week and/or month and decide what I'm going to include on the page.
