Above is a progress shot of a sample of an anticlastic form with spirals forming at the ends. It was formed with both metal and plastic hammers on wooden and metal forming stakes.

Above is a couple of progress shots of an asymmetric synclast formed with a raising hammer and a depression in wooden block.

Above is a sample of a double helix in the beginning stages. It started as a basic synclastic form that has been manipulated by hand to form the start of a spiral.

Above is a sample of basic foldforming. It is started by hammering the metal closed in the center of the form, like folding a piece of paper in half. Then it is annealed and opened up, creating the central crease in the form.
