How to write a pattern?

Abstract

Pattern writing is a creative, iterative process. For new pattern authors, however, it is often not obvious where to start and how to proceed. Although well-written patterns typically follow a strict format, the number of available formats push first-time authors right at the start to choose a specific format without knowing its advantages and liabilities. Furthermore, new pattern authors are often not aware that the order in which a pattern is published typically is not the best order in which to write the pattern.
