many a mickle makes a muckle
- (UK) A lot of small amounts, put together, become a large amount.
Mickle and muckle both traditionally meant "a large amount", hence the somewhat more logical variant "many a little makes a mickle". In Scottish English, partly under the influence of this phrase, "mickle" has, however, also come to mean "a small amount".
