Gluing beads

I’d like to ask: why are you gluing the beads on, rather than
melting balls on the ends of your wires to permanently hold the beads
on the wire? Or, could you make a tiny coil at the end of the wire
to keep the beads from slipping off? (Maybe I don’t really
understand your design, but I never regard glue as a "permanent"
answer…) Judy Bjorkman
