A novice glass bead maker recently asked me how on earth did I make my charm beads.
On the end of the mandrel, my dear.
The mandrel should be down into the bead about half way.
It's not easy being a newbie.
Ream them out until they're perfectly clean, let them dry and epoxy in a bail - viola!
Berries, blossoms, birds, bugs, balls... try it.
