You can get packages of wooden, glass, and clay beads at Walmart, Hobby Loby, or Marshels. Any craft store usually has them. You can get creative and put whatever in your dreads. One of my friends had very thick dreads and he decided to put a whole necklace in one and a spoon that he bent and wrapped around a dread.
