Aloha Johnp157,
As Paul clarifies with her, it's in relation to the building or room. Marie works with some clients with big houses.
If you are just hanging one up in a cubicle office, on of the tiny ones you mentioned may be all that's needed, since you are not curing the whole sector of the whole building or floor.
Look at the space you are curing for. What would seem small, medium, and large in that area? Now muscle check it. "Is this wind chime big enough to cure ____________?" "Does the wind chime need to be bigger?" By asking these questions you can fine tune activations and cures for your specific office, area, or home.
Much Love,
Shawn
