Actually, I didn't get it wrong - 

I used the popular idiom.  Commonly used to describe something to be improved by glossing over or prettying up a statement, it is more recognizable than the Shakespearean quote.  

But in your haste to try to make me seem wrong, you actually are the one who is wrong.  I was NOT referring to the Shakespearean quote at all - I was referring to Chesterton - to whit -  "If we are critical of the petty things they do to glorify great things, they would find quite as much to criticise (as in Kensington Gardens) in the great things we do to glorify petty things. And if we wonder at the way in which they seem to gild the lily, they would wonder quite as much at the way we gild the weed."

I don't actually have to look it up.
