These are neat little solar lights that you can hang in your garden or along walk ways or on your porch to give them that little detail touch none of your neighbors have. They make wonderful gifts. The solar lights cost around a dollar and the insulators, if you don't have some already, can be found at yard sales, antique stores or flea markets. They come in clear, green and blue. Ive seen these sell these at craft shows for 20.00 each but now you know how to make them and maybe sell them yourself!!! Enjoy!!!
