Iris uses clay as a medium to carry poetry in her beautiful tiles. They can be used for walls, floors, parts of furniture, 'read-as-you-go' footpaths and fountains, "a thing of beauty" either indoors or out in the garden. Each tile is unique, made individually by hand and decorated with words. Most of the tiles are inlaid, a process in which Iris carves the pattern in the clay while it is still wet. This technique has been used since Roman times to make patterned floor tiles.
