These sculptures began life as plaster models in artist Louise Plant's studio in Devon.
From her drawings exploring ideas about individuality and difference, Plant created dozens of small models.
Three models were chosen, refined and then enlarged to a scale suitable for the planned locations.
The enlargement involved fixing hard foam onto a core skeleton of welded steel rods. The foam was carved and sanded to form the shape of the sculptures. Plaster impregnated glass fibre sheets were layered over the foam to create a strong surface skin. Further layers of specialist plaster were then painted onto the surface to build sculptural volume.
Finally, the Ps were rasped, filed and sanded to give a smooth, continuous surface with no beginning or end. The enlarged Ps were then transported to Yorkshire for us to get on with mould making and casting.
