Make a template from heavy paper.  Cut each piece from a slab of clay.

Remove excess clay. Let slabs dry slightly to make your project easier to put together.

Add designs to sides of box.  Score edges of each piece.

You are now ready to begin constructing your project.

Before placing edges together, wet the scored areas with a sponge or water bottle.  Fill the seam with a coil to strengthen.

Continue construction, scoring, wetting, and sealing each seam.

Double check so that you don't miss any seams.

Smooth your seams for better quality and strength.
