Due to their simplicity, the creation of finger puppets is a common craft project for parents and small children and its origin as an art form is unknown.
In addition to their popularity as arts and craft creations, premade finger puppets are sold in a variety of venues[1] and are often included as companions to children books.
A set is usually just a group or collection of physically separate finger puppets, often intended to be used together in a performance.
Occasionally these units consist of two or three puppets (intended for adjacent fingers), but they are most commonly created as sets of five, designed to fit the entire hand of the performer like a glove, intended so all five puppets can be used simultaneously on one hand.
In the movie Hans Christian Andersen, the title character (played by Danny Kaye) tells the story of Thumbelina by singing to and manipulating a small finger puppet he has created to represent the fictional character.
