Choose a gravel color that complements the overall color scheme of your garden. The metal edging can be straight or curved, depending on the desired layout. Consider adding some potted plants or decorative lighting along the pathway to create a welcoming atmosphere. This pathway design is easy to install and maintain, making it a popular choice for urban gardeners.
