I came across this idea via Design Mom. The basic idea is to take small gifts and brightly colored crape paper strips. You start with the largest item and wrap it with the crape paper and then add another item and repeat until all the items are wrapped in the ball. Here are detailed instructions on how to make a surprise ball.
These surprise balls remind me if some gifts I gave my nieces when they were young. I wrapped their gifts in yarn. I took a small item and wrapped yarn around it until it was the size of a volleyball. I like the idea of having a series of small gifts to discover along the way.
I think it would be fun to have a series of small trinkets and photos that relate to a family member. It could focus on a single story with the items in the surprise ball help to tell the story. This idea has some great possibilities, I can’t wait to try this out.
