Olivia, written and illustrated by Ian Falconer, is still one of our favorite children's book. It's hard not to find her totally adorable. This little piggy is imaginative, spunky, and full of energy -- a lot like my daughter. So when I saw this Olivia birthday party on Dana Made It, I knew I had to share it. It's filled with easy DIY projects, plus creative party games and activities. Dana kept everything simple and focused on making it fun for the 3 to 5 year old guests.
