Just placing the lights in a sunny window lets them charge all day.
Lay them randomly on the windowsill and get cool geometric patterns on the walls at night.
Coil a 14 gauge wire around them and hang them from the valance to get a string of lights in the window.
This could be a nice way to create a starry night-light, without using plugs, in a bath or child's room.
It's a cost-effective way to add interest to a dark room, and save a little sunshine for when you get home.
