All the beads are strung on lengths of heavy (18 gauge) craft wire, and the loops which link each bead to the next are closed with wire wraps. On either side of each howlite bead is a wrapped wire bow which links it to the rest of the rosary and helps define it as an Our-Father bead. The way the howlite Our-Fathers contrast with the black onyx Hail-Marys reminds me of how the white Roman collar contrasting with the black clerical suit identifies priests. On either side of each howlite bead, is a wrapped wire bow which links it, but also provides distance and definition. All the wire is 18 gauge, all links use wrapped wire loops, and wrapped wire bows connect the crucifix and centerpiece and separate the Our-Fathers from the decades of Hail-Marys, providing for a very sturdy and durable rosary.
