Love this idea for Christmas. You could do this anytime. Would make a great night light in your bathroom Jan! You could dress it up for different holidays with just a little ribbon or this and that!!!!!
Go wireless and use a string of LED lights to illuminate your newly repurposed vintage birdcage, like ZuZuPetals. You can use rubber bands or clips to create the shape you desire for the light sculpture inside the birdcage.
