It’s a relatively easy project. You start by building a hexagonal shape to hang the swings from. If you want 5 foot swings then you need your braces about 7 feet apart each. You may want to leave one of the bays open so that people can go in and out but oh my goodness, what a great project.
You could build this in the yard and people would never want to leave your house. This would be such a neat project for summer evenings and you can either buy the swings or just build them yourself.
