Capturing the transient effects of natural light is one if the exciting aspects about working with these materials.  Colours and textures evolve and dissipate under different weather conditions along with an array of surprising light fragmentations from the unusual positions of the glass.

"Stained glass windows have been gracing the wall’s of church gardens for centuries. Helen can make this concept a reality for the domestic garden. Glass offers plenty of opportunity to play with light in the garden and rather than just hanging art onto a garden wall, there may be opportunity to incorporate art into a garden wall itself."
