One alternative is to glue the cupchain into a cord end, They have loops on the end allowing you to easily attach a clasp. Wire wrapping is another way to add a finish to the ends of cup chain. Wrap wire around the last "cup," so the wire is secure, then pull the wire into a cone so the end of the cone and the wire are securely hidden inside the cone. Finish the wire with a wrapped loop to attach your clasp.
