In a rare fit of craftiness/boredom, I made a couple mini pinatas following this guide on Ruffled. I'm not gonna lie. They're pretty time-consuming and I might think you're a crazy person if you make them for the entire party list, but have to admit the end product was really fun. They're hard eggs to crack; we ended up wacking them with C's Sigg bottle to get the party started.
Before I knew it Oscar had stuffed 17 Skittles in his mouth at one time. But luckily no pom-poms. Needless to say, the other one will be saved for a rainy day.
More mini pinatas here and here.
