Just carry around a small notepad and jot down a brief itinerary for the day along with anything you find particularly interesting, whether it be thoughts on the local food, strange customs, the people, aspects of daily life, or anything else. Oftentimes, one or two-liner
scrapbook titles are enough to explain what's up.
It can be as brief you like because the main aim here is to jog your memory when you start scrapbooking as it's easy to forget some of the finer details at the end of your journey. If you are with a guide, do some quick bullet points to remember interesting facts that you can use to explain a photo or describe a location. This is great for your scrapbook journals, fun info is always one thing you'd love to read again about a new place.
You can write down brief exchanges with the locals, funny comments someone from your traveling party made, or perhaps some amusing thoughts or anecdotes.
For those who want to expand on this a little more, keep a daily travel journal of where you go, what you see, and how you feel—you can even rip out the page and stick it straight in the scrapbook!
On the downside, if you're trip involves a ton of water time like scuba diving, island hopping, or a ton of swimming, taking your polaroid and a permanent ink marker is enough to jot down ideas and small snippets you can read again later on. They're also perfect for your scrapbook or journal.
