The kids and I had a lot of messy fun making these Easter eggs from yarn, and they look really cool hanging from the dining room window. It was like paper mache with string, and a great Easter project for kids of any age. All you need is liquid starch, flour, balloons, and yarn or string of your choice.
You can get directions from HERE as this in not my original idea.
Here are a few pics of the process and the end result.
