The key to the success of creating a similar balloon arch is variety of balloon colors and variety of balloon sizes, which you can create with how much you blow it up. I tend to like color schemes that focus on three main colors. For the Bhldn shoot it was pink, mint, and white. I then supplemented it with shades of those colors. I added in some balloons that are clear, some with polka dots for a bit more whimsy. For A Midsummer Mingle I worked with Partyland here in Utah (though they ship!) and they exposed me to the EZ Twist balloon maker which allowed me to add in twisted balloons into the arch. I LOVE the effect they created and I think it would be rad for so many applications.
