Polystyrene carving can be very effective for quick one-off pieces as well as forming the armature for more detailed sculpted clay modelling on a large scale.
High density polystyrene can also be used to shape accurate and crisp forms. These are generally protoype forms to prove a design or used as ‘plugs’ which are then moulded and reproduced into grp or composite materials.
Projects I have undertaken range from giant heads to full size trees and scaled up car interiors.
