* Use a swivel hook. A swivel hook is a type of hook that allows the wind chime to rotate freely, which helps to prevent the chimes from getting tangled.
* Hang the wind chimes in a sheltered spot. If you hang the wind chimes in a sheltered spot, they will be less likely to be affected by the wind and therefore less likely to get tangled.
* Use a wind chime with a long chain. A wind chime with a long chain will have more room to move, which helps to prevent the chimes from getting tangled.
* Periodically check the wind chimes and untangle them if necessary. Even if you take all of the above precautions, it's still possible for wind chimes to get tangled. If this happens, simply untangle them by hand.
