 == 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]]""."
