Knead your clay. Place the dowels either side of the clay and roll out a slab- ensure the roller covers the dowels as well as the clay to create an even depth. Cut out two side templates

Find a ruler, piece of wood etc to cut your remaining sides and base. The ruler pictured is 4.5cm wide. Cut two pieces your maximum side length and one your minimum width (see Step 2).

Using a clay tool or skewer, score each contact surface to be joined- around one face of each template shape, and all edges of the sides and base.

Paint contact surfaces liberally with slurry just before joining each piece. Start with adding the base, then sides. Press each join until slurry begins to escape and a mild vacuum seal is achieved.

Once sides and base are joined to one template, fill the cavity with damp newspaper. This will stop the last piece sagging whilst being joined and decorated.

Join the final template and take some time to smooth and check joins before wrapping in a plastic bag to harden slightly (the consistency of leather). This may take hours or days due to humidity.
