What is the origin of the idiom "odds and ends" and when to use it?

The idiom "odds and ends" has been in use since at least the 17th century and likely originates from the idea of miscellaneous or leftover items being a collection of various "odds" (unmatched or irregular items) and "ends" (small fragments or remnants). This phrase is used to refer to a collection of small, miscellaneous, or unrelated items or things. It is used to imply that these items are not part of a larger, organized whole and may be of varied importance or value.
