Create a whimsical and lighthearted atmosphere in your garden by placing a hand-painted sign with a cottage-inspired font that lists the 'Garden Rules.' Paint the rules on a wooden board and hang it on a fence or place it near a seating area. These rules can include fun and playful guidelines like 'Stop and smell the roses' or 'Weed out negativity.' This sign will add a touch of personality to your garden and make it a joyful space.
