Letterlocking

Letterlocking is a fancy way to fold and seal letters so that no one can sneakily read or tamper with them. It's like making a secret envelope that only the person it's intended for can open.

Imagine you have a piece of paper with a message on it and you don't want anyone else to read it. Rather than just folding it in half and sticking it in an envelope, you can use a special folding technique called letterlocking.

Each letterlocking method is like a secret handshake that only the person who knows the technique can use. It involves folding the paper in a specific way and then sealing it with wax or other materials so that it stays closed until the person it's meant for opens it.

Some letterlocking techniques go back hundreds of years, and they were used by important people like kings and queens to send secret messages. It was a way to keep information private so that nobody else could see or steal it.

Nowadays, letterlocking is still used by some people who want to add a little extra fun and security to their letters. It's a cool way to make your letters stand out and keep your secrets safe.
