1. Thread your cord or lacing through the key ring or lanyard hook. Find the halfway point so you have two cords of about the same length hanging from the connector. Thread both cord ends through the first bead from the same side of the bead.
2. Using the bead diagram for the witch keychain below, continue weaving the rows of beads. Pass one cord through the next row of beads, then pass the other cord through the same beads from the opposite direction as shown in the illustration. Pull both cords until the new row rests against the previous one.
Continue following the diagram, adding one row at a time to form your witch's pointed hat, hair, face, dress, and feet.
The diagram below shows how the two ends of the cord are threaded through the beads to make your Halloween witch pony bead keychain. The red and blue lines help you follow each cord as it passes through the beads. Click the diagram to open a larger version in a new window whenever you need a closer look.

3. When you've finished the last row of your witch's feet, the two cord ends will be on opposite sides. Thread one cord back through the previous row so that both cord ends come out on the same side. Tie the two cord ends together using a double knot or surgeon's knot. Apply a little glue to the knot to prevent it from coming untied. Once the glue has dried, trim the excess cord.
You can also try making this witch pattern with smaller beads, such as seed beads or E beads, to create a little Halloween charm or jewelry pendant.
