- Room layout: Consider a backdrop garland or fringe curtain to anchor the main seating or cake area; ensure there’s space for photos.
- Durability and reuse: Double-sided metallic or premium cardstock decorations offer better longevity; plan for storage after the event.
- Assembly time: Kits with multiple components may require more setup; allocate planning time and recruit an assistant if possible.
- Safety and comfort: For any outdoor use, ensure items are securely hung and do not block exits or create tripping hazards.
- Budget balance: If hosting a larger guest list, prioritize a few statement pieces (backdrops, fringe curtains) and supplement with smaller accents.
