Done + done. I brought the base of a book to New York last weekend, filled it with polaroids, tickets and business cards while we were there and then added 4x6 photos and parts of our map yesterday.
A travel album is a concise way to get travel photos + travel thoughts together in one place. My advice is to give yourself a lot of space in your book for writing. Each day, sit down in the afternoon and journal what you did that morning. Sit down in the morning and journal what you did the previous afternoon and night. It's surprising how quickly the little things fade if you don't get pen to paper.
I put blank transparencies into this book and they were the perfect way to "suspend" business cards within the pages. I took my polaroid photos sideways so I could punch through the white space and they would still be right side up in the book. After we got home, I cut up the map we used and "labeled" the locations of spots we visited.
Supplies : white cardstock, book rings, staples, Hambly Studios paper and transparencies, hole punch, white booktape, chipboard, American Crafts black slick writer pen, white Sharpie. ++ PS : the album on the road concept is totally something I got from Ali Edwards. Her travel albums are fantastic.
