Shape, texture, pattern, functionality, color, and so many other things inform design inspiration. For me, almost everything has potential to transform into a cohesive design plan. Keep your eyes open. Look up. Look down. Look for patterns. Look for texture. Look for variation. It won't take you long to see something that interests you.
The pattern from worn cement combined with a shock of green moss gives me ideas to transform a garden space, paint a wall, and think of life perspective.
I will post additional photos of a room inspired by the sidewalk as soon as I am able.
