DIY Balloon Mosaic* (*Some links contain affiliate links and I may receive a small commission for any purchases made.)

  • Foam Board. Depending on how big your mosaic is will depend on how many you will use. For my 5 ft, number 3 I used 3 for the number and 3 for the sides. Best place to buy this is at the Dollar Tree!

  • Hot Glue Gun and Hot Glue Sticks

  • Ruler

  • Balloons

  • Glue Dots

  • Number Template

  • Ruler

  • Scissors

  • Hand Pump or Balloon Pump

  • Exacto Knife

  • White Duct Tape

  1. Print and assemble number template. Using your Etsy download, print out the size for the mosaic. The option Iā€™m linking comes with templates for 1ft, 2ft, 3ft 4ft, 5ft and 6ft. Friendly reminder, the bigger the template, the more foam board you will need.

  2. Using your white duct tape, tape foam boards together.

  3. Use your Exacto knife to carefully cut out your number.

  4. Using your ruler, measure out 6ā€ of the length of the foam board and cut. This will make up your side pieces. For rounded edges, lightly score the foam board as to not go entirely through. Lightly score the foam board one inch a part. Pro Tip: when scoring, use your ruler as a guide as you go.

  5. Assemble mosaic. Using lots and lots of hot glue, carefully assemble the base to the sides of the mosaic. Using your side pieces cut your edges as you go.

  6. Fill up your mosaic with balloons and attach with glue dots or low temp hot glue.

  7. Enjoy! I hope this helps inspire your creations and would love to see them. For more visuals, watch the video on TikTok and tag me on Instagram!
