This is a DIY necklace inspired by dreamcatcher. I was impressed by the dangling spikes, so stylish but simple. If you are going to make this one, same colored O-ring, spikes(or other pendants), wire, jump rings, and chain should be required. And recommended beads size is around 2/3 or 3/4 the size of your O-ring.
