Great ideas for clay without clay -
Hand building techniques with other materials.... boy you could do a lot... and then the final project could be a project that combines all three (pinch, coil and slab) - trying to think of a material you could form a 'pinch pot' with that doesn't need water (or much water) paper pulp, teeny tiny with bread and glue dough... - outside if that is an option, ? Cardboard, leather, wood, rubber for slab... yarn, rope, wire, grasses, pine needles for coil.... - what can the students brainstorm?
Think on a different scale - really small clay projects (with sculpey if you are challenged with the location) - research different periods and cultures and have an entire history of clay - create a 3D timeline or shadowbox - a miniature museum.
What about using the weaving project incorporating cast off/found 'clay' - have the student search their basements and goodwill for the base -
Any chance you can get a quantity of air-dry clay? That way you could at
least do some clay?
Other 3D projects that I've found successful.....
