Beautifying your yard doesn't have to mean you are being frivolous. The ornamental things can be relaxing and promote better health. Others feed animals and that has it's benefits to the rest of your yard or your relaxation.
Water features are one of the things I love in a yard. I find the sound of water to be nature's music and it gives me more relaxation than whatever new product is out there or an expensive night out for dinner and entertainment.
These can be expensive if you run right out and buy a packaged item from the nearest lawn and garden store. We are frugal and we can do it ourselves! What water features do you have? Ideas on how to get them installed cheaply?
