Friendship Books (FB for short) are traded by many pen pallers. They are small handmade booklets that are passed from person to person, each adding his/her name and address (many times by label). Most people add information about themselves such as age, interests, hobbies, etc. Some write that they would like new pen pals. Some add stickers or other types of decorations. When the book is full it is mailed back to the person it was created for. Fbs are started as a way to thank a pal, to look for new pals, and for collecting. It is very interesting to get a full fb back because you get to see all the places they have been...though many states and countries. The designs are full of variety. Some are very simple; others are complex art projects. Some people make them of out of crap paper. Others neatly cut fancy paper and emboss it with rubber stamps. There are no limits to the designs people make. You do not have to sign fb's if you don't want to, just pass it along to someone else. Fbs require patience; they can take years to fill (especially large ones). It is best not to make fbs too large because you don't want to pay too much for postage and have a hard time fitting them in envelopes.
Friendship sheets are just like fbs, but instead of a booklet format they are just one sheet of paper.
Slams are similar to fbs. The first page(s) is the sign in page. This is where you write in your name and address or stick you label, usually next to a number. On each of the following pages is a question. Under the question all the signers add their answer next to their number. Some common questions are: "what is your favorite movie?", "would you like more pals?", "name your favorite TV shows".
Crams are fbs on a small scale. The point is to cram many addresses on to a small piece of paper. You do not write information about yourself or anything that will take up to space. Many are for address labels only.
