I also have a backyard. I've been working on its design for several months already. I've already installed a patio with gazebo, decorated it with bulbs and lantern and bought a wood furniture kit. Now I'm going to add the glow stones. I was lucky to find a good source that provided me with all necessary information. They look great and it is possible to see the very radiant glow and even the afterglow lasted throughout the night. Does anyone have such stones?
