Read Dr. Seuss or nursery rhyme books to help give you inspiration to write riddles, explains Scavenger Hunt Fun. These books can give you the feel for writing rhyming clues. If you have kids, you can search through their bookshelves, or you can go to the local library.
Look in the books for rhymes that you know or ones that are easily remembered. It is best to find rhymes that use words that can be easily replaced with new words. You can use these rhymes to help write riddles of your own.
Take the rhymes you find in the books, and change the wording around. With this method, you can create all kinds of riddles. Use your own clues in place of the words to create a new rhyme of your own. For example, the rhyme "one, two, buckle my shoe" could become "one, two, find my shoe. My yellow sneaker holds a clue," as stated by Scavenger Hunt Fun.
