Posted:You need a pair of chains that our for fire. Ones that are made of metal. As for attaching the wick if you go to the Home of Poi Shop you will find complete chains to buy or just the clips that attach the wick to the chain/cable you are using.
Posted:I forgot to mention that you can find clips at hardware stores or fishing stores. Just look at the ones in the shop to give you an idea and remember that it has to be strong so it will not come loose when you are swinging, because of the weight/force.
