Lead has been used for centuries to build windows. The uniformity and flexibility of the came makes it easy to use and creates a beautiful panel.

There are a variety of shapes and sizes available to use. Try mixing sizes in a panel to add interest and highlight areas within the panel.

When using thicker or textured glass a high heart came will save you the effort of grinding every piece.
