People also sometimes make FBs for someone else rather than themselves, in which case they write the name and address of the recipient on the front/at the top.
Some people find friendship books fun because you can see where they have been in a trail back to the original sender/recipient.
The German friendship books (or poetry albums) serve a similar purpose but are kept, not sent away.
The information given about oneself often includes quotations, poetry and worldly wisdom.
Friendship books that require entrants to make drawings, use stickers or magazine photographs are known as "deco" friendship books or just simply "decos".
Glitter, sequins, feathers and other scrapbooking supplies are frequently used in "decos."
Crams are like friendship sheets or book, but no one includes any personal information.
Some are more plain with the words simply written in them, others are as artistic as decos with pictures and other ornamental adornments.
