The Japanese are masters of using asymmetry in design. You see it in their lithographs, their architecture, and in their gardening techniques. Using asymmetry is one more element that can create interest within the composition of your design.
In these earrings, I use rusty brown Czech glass nuggets and transparent brown nuggets along with copper in an inverted asymmetrical design.
