I was recently hired to make a 6 ft. tall, not even counting the bubbles, balloon wine bottle with Happy Birthday Sean in balloon letters on it.
I took my experience making Dalek balloon costumes and applied it to this project. I had to make it in 3 separate sections to be attached on site in order to deliver the piece. The bubbles I made on site as well.
Of course I took inspiration from Brian Asman from the Unpoppables, specifically episode 3. He made a giant wine bottle in that episode though he used 646’s. I went with 350’s and 260’s as I needed the pieces to fit inside my car for assembly. He doesn’t teach you how to make it in the episode, but it is useful for inspiration.
