I found a generic black faux-leather scrapbook at Michael's, one that has a binding that can be opened up so that you can add and rearrange pages. The pages also have plastic cover sheets. I guess the purpose of these would be to protect your scrapbook pages, but more importantly, those plastic covers were the perfect pockets in which to stick the important wedding related paperwork. I divided it up into sections (ceremony, flowers, fashion, etc.) and began gluing pictures found online and in magazines to the pages. Once the contracts started coming in, they got tucked into the plastic pockets on the adjoining pages, nestled in between design inspiration.
I bought a fancy green pen, and sometimes I even scrawl ideas directly on the pages. And in the very front of the book, I glued in a checklist pulled from Real Simple Weddings and thrill at checking things off that list. It's become like a cell phone or or a security blanket -- something I simply can't be without for very long.
