I wanted to use Hill Tribe silver, and was trying to find a bead cap that would look good with it. Bali looks just too intricate and delicate with it. One of those silver capped beads would look good with it, so I was thinking about asking Tink and others where they get their "rivets". I finally found them in the new Rio catalogue on page 408. The diameter is
11.1 mm, and it's very, very shallow. This is a great addition, for lampwork with its straighter sides.
