I saw this type of swing at a garden are behind a local hospital. There were 3 of them and I fell in love with the design. I was unable to find any similar templates anywhere online. So, I took posterboard, take and a marker to the garden area and drew out the template for the bottom and the back. After taking a few picture and measurements, I was ready to build my own. I built if from pressure treated pine and only used galvanized fasteners for a long standing project. It is mounted where our previous swing once was.
