i've been totes into the necklaces at totokaelo lately, so i picked up some hexnuts from the hardware aisle, to make my own version.
jump ring (from a crafty store)
chain (from a crafty store)
hexnuts (from the hardware store)
1. measure length of chain. (i used 28", but it could be shorter or longer)
2. string on hexnuts. (i used five, but there were eight in the package)
3. attach jump ring to close the chain.
