Steve and I had a big surprise to share with Trevor related to my newly-acquired membership as a Creative Professional in the Craft and Hobby Association. Rather than tell him outright, I wanted him to decode the news. A surprise is even more fun when you have to work for it, right? Right!
I started by writing my five-word message in large letters on a piece of copy paper. I put a second piece of paper over the first and used a black pen to draw a line under each letter. I went to my stamp collection and pulled out one small stamp for each of the unique letters in my message. I stamped each letter in the message with a different stamp. As you can see, the letter represented by the red heart appears 7 times in the message.
Next, I made a key. I randomly assigned each letter of the alphabet to one of the numbers from 1 to 26.
Finally, I took a third sheet of copy paper and used my key to stamp each item the correct number of times. There are 10 red hearts. So, according to the key, 10 = D.
In case any of you want to try decoding it, I'll wait a day before sharing the solution!
