Keep memories of your travels using a zip-lock bag and a file folder. Glue the zip-lock bag inside the folder and use it to hold small items, such as business cards, ticket stubs, and receipts, that you pick up during your trip. Use the main part of the folder for larger items, such as menus or maps. When you get home, take out the receipts, label the folder, and file it for safekeeping. It comes in handy for scrapbooking or as a guide for someone you know who is planning a trip to the same place.
