I wasn’t really aware of the Pandora line until the recent discussion about it on Orchid. If you’d like to make beads that work with them, this line of fine silver bead cores from Metal Clay Findings will make sizing much easier.
Here’s what the company says:
The bead core’s diameter is sized perfectly to fit the popular Pandora™, Chamilia™, Biagi™ and Trollbeads™ type bead charm bracelets.
