Advanced beveling techniques
Most stained glass artists are aware of the standard 1/2" bevel around the perimeter of the glass. One technique that I have enjoyed using is to bevel the piece to a peak, but not down the center.
To illustrate what I mean, take a look at this drawing:
This piece represents a standard 1/2" bevel around the perimeter.
This piece represents the bevel to a peak, but off center.
Notice how different the look is, even though the actual piece is from the same pattern.
Another nice look is to vary the peak to deliberately not follow the edge of the glass:
It is a nice look for leaves.
