Scrapbooking is an artistic hobby that involves creating visually interesting collages from scrap materials. Some folks employ it to memorialize the big moments of their lives—birthdays, graduations, and other special events. But you can scrapbook about just about anything, and it can even be a purely artistic expression where you use paper, ribbon, and other scrap materials to just make something beautiful in a book or on a page. Since it can be done with materials you have lying around, the only cost usually involves a bit of glue and perhaps the scrapbook itself.
