Diapered I m happy to agree with you that diaper is a correct description of the pattern of windows set in a diagonally hatched pattern and I love learning new stuff thanks But I ve undone your undo because I don t agree that it s either clear or correct to describe the shape of a pane of glass as diaper shaped I consider that equivalent to describing a semi circle as wave shaped a component part of a pattern isn t the pattern Perhaps the current usage of the word isn t accurately reflected in diapering or wiktionary Anyway if I remain wrong A distinct possibility I m sure please rather than undoing my edit replace diamond shaped with relevant article supporting that usage diaper shaped
