An automated multi-purpose quilling device includes a housing and a driver element. The housing accommodates an electrical unit. The housing defines a through-hole and is configured to receive at least one tool attachment to perform one or more functions of quilling. The driver element is attached to the electrical unit of the housing. A first end of the driver element is placed onto the electrical unit within the housing and a second end of the driver element protrudes externally from the through-hole. The second end of the driver element is configured to receive the at least one tool attachment. The driver element is further configured to rotate when actuated by the electrical unit and in turn operate the at least one tool attachment.
