Here is a story I like to call "Goldizane and the 3 Tuques":
Goldizane had lost his winter tuque and was getting colder by the day. His wife earnestly took on the challenge of making him the tuque of his dreams (without a pattern might I add). The first tuque she made was too big. The second tuque she made was too small. And of course the third tuque she made was just right.
