Plan out your walkway by deciding shape, direction and endpoints. Do you want a formal or informal appearance? Will your walkway be a straight path to the garage, or does it need to curve from your back door around the house or around a group of trees or a flower garden?
Using flagstones with unique shapes creates an informal impression, as does placing stones randomly with different distances between each. A more formal walkway will have stones set close together with uniform space between each one, as well as squared corners and more traditionally shaped stones.
Measure out the walkway’s dimensions with a tape measure. It is up to you to decide how long or wide you want your walkway. A good rule of thumb for a path width is at least 3'.
Using garden hoses, lay out the shape of your walkway with this measured width. Be sure that your path’s width remains consistent. Measure it again and again as you lay down the hoses. If your path will be straight, you can also use wooden stakes and garden twine to mark the path. If you use stakes, drive them into the ground in intervals, using a hammer and attach the twine to each stake at the base. Keep in mind that stakes and twine won’t work for a curved path. When using hoses as a guide, lay them down in the desired shape of the path and then spray landscaping paint to mark the path’s outer perimeter. Spray along the outside edge of each hose. Let the paint dry and then pick up the hoses and put them away.
Once you’ve bought your stones and have them on site, lay down a few to make a rough layout and to make sure it will look the way you envisioned. Remember that flagstones are not uniform in shape and size and don’t need to fit a set pattern; however, they should work within the dimensions of your marked path. Some stones may need to be cut or shaped when you lay them down (see Step 3). Pick the test stones back up and set them aside.
