If you follow just about any European bead stitching blog, then you have seen these bangles derived from a pattern by Puca at Les Perles de Puca. Actually, I found details about how they are assembled at the French bead forum Histoire de Perles. They are also very similar to Sabine Lippert's A Square and His Friends pattern. [Her English language book will be realeased in May 2012 by Lark!]. These bangles and Cynthia Rutledge's Honeycomb Bangles seem to be in every French or Italian blog. I'm not usually into so many crystals, but I was drawn to these bangles particulary since I could stitch each with just Delicas, 11/0 seed beads, and some 4mm bicones.
