If you have the space, create different vignettes for different purposes — a table tucked into one corner and lounge seating in another. It encourages guests to wander and experience the garden from different points of view. I love how the simple peninsula of gravel defines the table area and how mis-matched pots and planters sprinkled around the space soften the hardscaping.
