Where does the term a pigs ear originate?

The term "a pig's ear" originates from the phrase "to make a pig's ear of something," which means to make a mess or do a poor job. This expression likely stems from the idea that a pig's ear is considered an imperfect and unattractive object, symbolizing a flawed outcome. The phrase has been used in English since at least the 19th century, illustrating the connection between the idiomatic expression and the perceived messiness associated with pigs.
