Retro Cane is a polymer clay cane made using an extruder. It features a characteristic design of squares with a concentric pattern inside each square.
To make a Retro Cane, you will need to load logs of polymer clay in at least three or four colors into an extruder with a square opening. Push the clay through the extruder and cut the obtained cane into 16 equal parts. You will notice that the colors vary along the length of the cane. Stock the obtained parts (4X4) to obtain the Retro Cane.
This is how a Retro Cane looks like.
