First, you need to do some preparation and research. You need to consider the overall look you want to have on your property. Do you want a glossy modern concrete or a world gravel look? You can have the old-fashioned stone or brick design. You need to look on the different walkway material that is available at your nearby hardware stores. Get the material that will look best and one that will work best in your yard. You can get a lot of ideas from home and garden magazines and websites that may contain walkway design and material.
Choose the path that you want the walkway to follow. However, you need to keep in mind the design of your garden and property. Decide whether a straight or curved work will work best on your property. You can have meandering walkways around statues. Avoid as much as you can to install the walkways under large trees because the roots may eventually damage the walkway as the tree grows. You can lay the walkway next to flowerbeds to make them look more pleasant. You will be able to water and care for the plants with the walkway next to the flowerbed. After you have decided on the path in which the walkway will follow, check on the actual placing of the path.
You will need to follow a certain approach depending on the choice that you pick. If you have chosen to have straight stone walkways, you just need to stand on one end of the imagined path. Tie one end with a string and hold it onto something and then unravel the string as you walk over the planned path to the other end of the walkway. If you are contented with what you see, you can secure the string marking the border the walkway. Mark the right and left borders of this line leaving a gap as wide as you want the path to be.
If you have considered to have curved walkways, you need to use something flexible like a hose. You need to stand on one of the paths and unwind the hose in suitable meandering curves as you walk on the other end following the imaginary path. Unwind another hose on the other side keeping the desired width of the walkway matching the meandering path you already established with the first hose.
