I've been told that some people are having difficulty finding the exact glass beads for the Four Corners bracelet I made for the Nov/Dec 2008 issue of Step by Step Beads. So sorry about that! Here are some tips for finding alternatives:
* Look for "diagonally drilled", "corner drilled" or "diamond shaped" square or diamond beads.
* Beads should be flat, not cubes.
* Beads need to be drilled at the corners in order to work the pattern.
* Common materials for this type of shape are gemstones, shell, and pearls. Some glass, but not as much.
* Watch the bead size -- 10-12mm or so
Here are some photos I found online, so you can get an idea of what kinds of beads to look for (this is not a shopping recommendation--I don't have any personal connection to these companies):
