At that time, several guilds were working on the wagon construction within the same shop; the carpenters assembled the box and the wheels with hardwood; the blacksmiths melted and nickeled the metallic elements, and the painters prepared the background colors. Finally, it was the filete artist's turn: they decorated the wagons to the owner's preferences, within the constraints of time and money. Generally, the work could be divided into two styles: "more full" or "less full" and typically, each wagon was an elaborated piece, a product of the work of different craftsmen.
The filete quickly developed into higher levels of complexity and severals techniques and decorative elements started to form a collection that made filete a unique genre different from anything anyone had ever seen. Regarding motifs, most of them were taken from architectural elements of the time, as well as some ornamentation sold in local paint shops. The most recognized style is the neoclassic or "grotesque", which is known for an elaborate development of spirals, and not Art Noveau, since this last style is characterized by the "whip line", absent from the first filete works.
