I used 6 balloons of each color above 1 package each (81 ft) of coordinating streamers cut into approximately 8 ft strips to make this colourful backdrop for my Ruby's 1st birthday party. It turned out exactly how I wanted it to (I got the idea from Pinterest, of course! It cost under $10 with supplies from Party Stuff.
Daisies & Donuts First Birthday Party....love the backdrop decoration behind the table. Streamers (two strips of streamers together and slightly twisted and attached at top and bottom.) accordion fans and tissue fans. Lot of cute ideas and descriptions at site.
