bold as brass

Brass as Base Metal

going too far is as bad as not going far enough; beyond is as wrong as falling short; too much is as bad as too little

a face as long as a fiddle

a letter sent as thanks for being treated well as someone’s guest

A miss is as good as a mile

a problem as old as the world itself

as bald as a coot

as best as one can

as big as life

as black as one’s hat

as blind as a bat

as blind as an owl

as born as known

as broad as long

as busy as a bee

as cheap as dirt

as clean as a whistle

as clear as a bell
