I really like the white marble and set in flagstone.
plan out your walkway with a garden hose, being sure to add those nice rounded curves and turns if possible.
Dig down about four to five inches. Remove the soil and then lay down a good anti vegetation mat, then some sand.
Use that green landscape metal edgine to block it all in, then pour the marble and set the flagstone about walking distance, design a rest station or a out curve for a set tee or something. Line with malibu lighting.
These look nice and very inviting for visitors and make for a safe entrance. Place the flagstone where each natural foot step will hit one.
