Use an old tire to create a small backyard pond. My kids, 3 sons, have been helping with yard work and planting. They keep asking for a pond. I think this is a great DIY project to do outside with them. Looks simple.
Did this several years ago with my milk can, before turning it into large "urn" with lighting in my Secret Garden! An outdoor side table made from an antique milk can! Includes directions for adding an umbrella.
