Theme: Curious George
My son loved monkeys, so we naturally chose Curious George as the theme. It's hard finding party supplies for that theme, but we finally found some. One of the most helpful sites was pbs.org. That's where the masks came from.
I made the cake and cupcakes myself (rings from BirthdayDirect.com). We used primary colours as a base.
Cute Curious George cupcakes.
The masks were great for all ages, from pbs.org
I made the pennant banner from store bought letters (teachers' supplies), construction paper, and ribbon. The favour bags came from BirthdayDirect.com. I just put them together and filled them with candy, stickers, and a banana. We also used bananas as decorations. Some of my son's monkeys were also used as decorations, and we used primary color streamers and a red 99 cent table cloth
