The decorative designs are created by fusing coloured glass, ground frit and glass stringers onto two layers of clear glass. The glass is then fused together in the kiln until it becomes one piece. This can take over twelve hours to reach full temperature and cool to room temperature. Any detailed gold leaf or other paints are then applied at this stage and the piece is then re-fired and slumped into a mould at a lower temperature.

For her scenes, Stella makes detailed drawings of the design prior to cutting the glass which must be accurate to achieve a near seamless fit. The result is an individual artwork which shares a personal engagement with the viewer. Dichroic glass is also a feature of Stella's work. This glass is highly reflective appearing to have one colour when viewed in transmitted light and another in reflection and a third colour when viewed at a 45 degree angle.
