6. Activity – Surfacing by Clay Modelling Create an armature by stick the two cardboard profiles on a piece of Styrofoam Put clay on the armature Drag the clay surface-by-surface using steel ruler or clay tool

7. Activity – Surfacing by Foam Modelling Check and adjust the flatness and angularity of the grey foam stock Trace the two cardboard profiles on the adjacent sides Rough out the profiles Sculpt the surface according to your flow- line sketch Finish one patch before you move on to another, delineate your patch boundary
