To add the first round of embellishment, pick up 4 size 15 metallic gold seed beads. Count two cylinder beads down in the same row from the bead you are coming out of. Pass needle and thread through the next cylinder bead in the row (third bead from the one you are exiting). Make your pass go in the opposite direction. If you are coming out of the top of the bead, pass through the third bead from the bottom. If you are coming out of the bottom, pass through the third bead from the top.
Continue all the way around the tube.
