Hang them inside, hang them outside!
These are a fav of mine because I love the sound of wind chimes. They are soothing and peaceful to me.
I have clients who love to hang them on the front or back porch. Others love to hang them inside rooms where they regularly open windows and let them chime through the house. Some hang them in the kitchen to use as energy healing while prepping or cooking food.
Hang them wherever you want some extra energy to chime in and help you reset your atmosphere while letting the crystals personal energy help you cultivate a space that feels amazing.
