Stoichedon is like writing letters in a row, one right next to the other, without any spaces in between. It's like making all the words in a sentence look the same length, so they line up really nicely. It's kind of like a puzzle, because you have to figure out how many letters can fit in each row to make it all work out. Imagine drawing lines on a piece of paper to write your letters on, and trying to make sure each line has the same amount of letters. That's what stoichedon is!
