Clear the area you are going to make your flagstone pathway in. This includes removing weeds, grass or roots. If necessary, you may have to use a shovel to dig up any roots that are in the way.
Spread sand over the area where you intend to lay your flagstone walkway. Smooth it out carefully with your steel rake. Ideally you should have about a two-inch sand base to lay the flagstone down upon.
Wet the sand lightly with a garden hose and smooth it out again with the steel rake.
Lay out your flagstones. Since flagstone comes in irregular shaped pieces, they do not have to be laid in a perfectly symmetrical pattern. You should leave at least a few inches between each flagstone, though, so that the gravel will settle in the cracks between the stones.
Pour gravel between the flagstone pieces you have laid for steps. Small, thin gravel is usually used between flagstones and should be available at home-improvement store garden sections.
Sweep excess gravel off the flagstones into the cracks between the stones.
