This pattern from BeadSmith by Marcia L Balonis uses: 30 honeycomb beads, about 144 O beads, 5 gms each 15/0 and 11/0 seed beads, 30 3mm bicones, 16 4mm fire-polished beads, 28 3mm fire-polished beads. These quantities make 5 3/4 length. To add about another inch use 6 more honeycombs, 6 more 3mm bicones, 3 more 4mm fire-polished and 6 3mm fire-polished. This is a basic right angle weave for the spine with fill in using the larger beads. You can also use silky beads.
