I cut off all loose ends of fishing threads. It looks pretty. This model is the largest one (about 22.5cm x 22.5cm x 22.5cm) among all beadworks I had now. Again, I used two different colors of 6mm beads to make it. Red beads are used to make 7-bead groups (heptagons) and white beads for the other 6-bead groups (hexagons). CNTs in this structure belong to the zigzag form of CNTs.
