To embellish the bottle, select a variety of beads from a craft store. Mix colors, or use different shades of one color.
String beads onto bead wire, occasionally wrapping the wire around a bead and through the hole again. This anchors some beads in place but allows others to playfully slide along the wire.
Wind the beaded wire around the neck of the bottle, twisting the wire ends to secure. Cut the ends short and twist them underneath a bead so the wires won't catch on fingers.
