One approach that worked was to build a pattern in one article, then follow that template for the next. It was legitimate because the four articles had to explain the four steps of a process. The natural progression was to do "A", then "B", "C" and finally "D" to each object that the person would find.
Writing Tip: If there is a pattern in the subject matter, then use that pattern in writing.
Counter-Tip: Do not follow a pattern if the subject matter does not.
