Start by picking a flat spot in your yard and measuring out a rectangle about 10 by 15 feet. Dig down four inches, lay a weed barrier, then fill with crushed stone and pack it tight. Mix sand with a rubber infill for realistic roll, spread it an inch thick, and level with a screed board. Install synthetic grass with a power broom to stand the fibers up, then cut a hole and drop in a plastic cup. Finish by rolling a ball around to find and fix any bumps.
