1) Take one of the headpins and snip off the ball with your Side Cutters. Create a simple loop with your Chain and Round Nose Pliers. Open the loop and attach it to one of the Frog Prince charms. Close the loop securely.
2) Thread a green Czech bead onto the headpin, and create another simple loop, perpedicular to the direction the other loop is facing. Before closing this loop, attach it to one of the center link in the 18" length of chain, and then close this loop securely.
3) Open the two Jump Rings and use one to attach each half of the Toggle Clasp to either end of the 18" of chain.
