11th Birthday Decorations Set Blue Theme Happy Birthday Banner Bunting Balloon Decor Photo Backdrop for Boys Girls Tweens Party Supplies Celebration Decor Event Bundle Bunting Set Party Pack

• Blue takes the spotlight: six navy blue and six light blue 12‑inch latex balloons team up with six blue confetti balloons to build a cool, photo‑friendly palette. Layered blues frame the number foil and the HAPPY BIRTHDAY bunting so your background looks neat on camera and sets a cheerful mood for games, candles and group photos.
• Complete kit for the 11th: blue HAPPY BIRTHDAY bunting, two 18‑inch blue star foil balloons, two 18‑inch blue heart foil balloons, two 32‑inch blue number foils to match the age, six navy blue 12‑inch latex balloons, six light blue 12‑inch latex balloons and six blue confetti 12‑inch latex balloons. Includes ribbon for quick setup. Use helium for floating displays or air for taping and tying.
• Built to last the whole party: thick foil with firm seams and high‑grade latex help reduce popping and keep colours bright. Numbers float beautifully with helium; with air you can anchor them to walls, doors and balloon arches using the included ribbon. Ideal for living rooms, halls and sheltered outdoor spaces so your display stays smart for hours and survives the final round of photos.
• Made for photos and video: the clean blue palette flatters skin tones and makes cake details pop. The oversized number keeps the age front and centre while the bunting and balloon clusters add depth. Perfect for Reels, Stories, keepsake albums, invitations and thank‑you notes—memories that still look good next year.
• Cool look for 11: two digits make a strong centrepiece and look dynamic in group photos. Ideal for tweens who want something a touch more grown‑up—clean lines, confident blues and a background that suits both party games and cake‑cutting selfies. Great for living rooms, halls or club spaces.
