This was a fun piece to make. I did a necklace a while ago that had some stick pearls in it in place of the oxidized copper tubes. But I used dark gray pearls and I only had 10 or 12 of them, so they didn't have as much impact as I'd hoped for. This one came out more the way I intended. I've found that if I alternate 1 or 2 octahedrons with what I guess you'd call a triangular prism, you get a blend of firmness ( from the octahedrons, since they're all triangles) and flexibility (from the prisms, since they have squares for the sides with a triangular cross section) that works pretty well. Anyway, I enjoyed making this.
