How to Make Leaves using St. Petersburg Stitch

From Jennifer VanBenschoten, former About.com Guide

On each side, pick up a size 15 seed bead and pass needle and thread back down through the three beads added in the previous step. On one needle, pick up four size 11 seed beads and pass needle and thread through the remaining beads of the row. Pass needle and thread from the other side through the beads just added as well.

Choose one side (it doesn't matter which one) and knot the thread in the beadwork, weave the thread in a bit, and then trim close to the beadwork.

You are now ready to add the "veins" of the leaf.
