Another aspect of his creative process, developed early in his artistic career, is his tendency to work on several sculptures at a time. Fitzgerald has coined the term "litters" to refer to his groups of works. The works in a litter can have direct visual connections to one another, but the term predominately refers to the shared time period in which the sculptures were created. Some of the visual connections are related to current metal supplies, or the mode of manipulation. The main definition of a litter is that the works have shared his creative energy. Generally, Fitzgerald works on between three and six sculptures at a time. These works can vary from small tabletop scale to large outdoor sculpture. Although he may be working on several pieces, each work receives its own undivided attention. He may spend several hours working on one sculpture, but there are always other works that are in process. If he takes a break from a troubling spot, or needs some contemplative time away from a work, he always has another work in a different stage of completion to deal with. In a down moment, a new sculpture may begin. The aspect of working on litters allows him to continually be in the act of making aesthetic decisions. The works and decisions can and do affect each other, but each sculpture is completely unique.
