From the makers:

“Each sculpture is an original creation--no molds are used -- everything is one of a kind.

The process starts with a metal/wood or plastic armature that is then built up with layers of rubber, plastic, metal, plaster and clay...each piece will have approximately 13 separate materials interlayered.

It takes between 2 weeks to a month or more of daily dabbling to complete each sculpture--depending on its size and complexity.”
