I was delighted when Lynne Ann Schwarzenberg published her gingko cane directions in the April, 2012 issue of Polymer Clay Cafe. The cane is fun to create, and the resulting leaves are as varied as you make them. As you can tell from the photos here, I've finally made some canes and created my own finished shapes.
The two pieces below are pins. One a cascade of gingkos, the other a swirl of leaves.
The group above has pieces made from a different cane - one in more muted colors and slightly smaller shapes. The leaves in the three-piece pendant on the left swing and move individually.
