We had the big Rainbow, Unicorn party for my daughter's 6th birthday. It was a success! It took a lot of prep and hard work but not a lot of money. Everything was homemade and nothing was difficult to do. Here are a ton of photos of the decor. I'll post more showing the actual party in a separate post.
The main table filled with homemade appetizers and desserts.
Fruity Pebble Treats & layered Jello
Oranges filled with Jello & chocolate covered pretzels.
Otter Pop Slushies... the biggest hit of all.
