I love hanging them in the windows of my house.
It's so easy to do. I attach the crystals to ribbon.
Screw in small eye screws into the window frame, then tie the ribbons to the screws.
Put them across the entire window for a really whimsical look.
I especially love the ones hanging in the Eastern bedroom windows.....it's so magical waking up to rainbows!
Now cleaning the crystals is a whole different experience!
