I used 12 cushion cut citrine beads, 10mm x 10mm. 14 cushion cut carnelian beads,15mmx10mm. 10 oval cut amethyst beads, 10mm. One amethyst briolette center bead, 20mm x 15mm. This design will make a 28 inch necklace chain.
First gather the beads and lay them out on the mat. Begin to arrange the pattern of the beads on the mat, leading with the smaller beads near the back and around the curve of the neck.
