Write a Coded Letter

Wednesday, October 10, 2012

My sister and I were obsessed with all things SPY when we were young, so there was never a question who'd I send my first coded letter to! Since neither of us grew up to be part of the FBI (or so you THINK!), it might seem a bit kiddy, but being a little young at heart can sure put a smile on your face. This letter is a blast to send and get, so get ready to engage your brain!

1) Start with a rough draft of your letter, written normally. While it doesn't have to be as short as a Pictionary Note, it probably shouldn't be too long. Remember you still have to encode it, and someone has to have the time to de-code it too!

2) Decide what type of code you are going to use. I made up a simple substitution code using a combination of letters and symbols. However, don't think that's the only type of code you could use! Check out this site to find out about a multitude of different codes good for writing. 

3) This step is optional, but, if you've never sent your recipient a coded letter before, you might want to give some instructions or a hint as to how to de-code your letter. I wrote out a key for the code I used at the bottom of the first page.

4) Write your letter out in code! If you are not very sure about your code, you might want to make a second draft, this time using the code. I skipped that, and my final draft was the first time using the code. Whatever works for you is best.

and Presto- you are ready to being mailing stuff out, Mr. Bond!

Hint: You miiiight want to keep a copy of any decoding tools you use, in case you get a like letter back in the mail! (I forgot to do this, so, Danyon, if you're reading this, take note!)

  2. I too wanted to be a spy. I was obsessed with Harriet the Spy and later Veronica Mars (she was basically a spy). So I think this is pretty awesome.

  7. I did this when I was a kid and then was really excited to find it in Keri Smith's Finish This Book. I wrote a letter to my friend in it and I think we overlook code usage too much!
