The Lost Art of Letterlocking
Good morning, Axelle!
Before envelopes and sticky seals, people had a clever way to keep letters private: letterlocking! It's like origami for secrets.
The Big Question: How did letterlocking work, and why was it so important in history?
The Mission:
1. Learn what letterlocking is and how it was used to secure messages.
2. Try folding a simple letterlock yourself (maybe with a piece of paper).
3. Find out how spies and queens used this technique to protect their secrets.
Did you know? Some letterlocked letters were so secure that they had to be cut open, leaving a telltale pattern that revealed if someone had snooped!
Have fuuuun!!!
Onward and Upward,
Mama & Papa
