We use 3D foam cutouts, layered shimmer panels, and organic balloon garlands that wrap around the structure to create a multi-dimensional backdrop. This technique transforms a plain wall into an immersive setting, making the unicorn, butterfly, or mermaid theme feel tangible and life-sized for the birthday child. Our approach to fantasy themes is structural. For butterfly themes, we often mount large, intricate wing cutouts onto greenery or wooden walls to create a garden effect. For mermaid setups, we use silver shimmer walls that catch the light to mimic the ocean surface, paired with seaweed and tail props. For unicorn parties, we prioritize pastel palettes and marquee lighting to achieve the correct aesthetic. We recommend our 3D Themed Decor package for these specific themes, as the physical cutouts and props are what define the visual scale. Our setups are modular, allowing us to adapt the theme to a banquet hall, a home living room, or a garden. Each installation typically requires four hours of prep time on-site to secure the backdrops and assemble the balloon structures. When you plan your event, keep in mind that the height of the ceiling in your venue will determine the size of the balloon arch we can implement. We operate throughout Bengaluru and Mysuru and can work with existing venue features to integrate our designs. ## About Event Architects We are Event Architects. We treat every birthday as a design project, whether it is a small house party or a large celebration.
