We used these jars from Ikea to start with but any jar would do, really. We also made a gigantic list of questions, like the ones here for example. We let the girls be in charge of cutting the questions into strips and then they folded them into quarters and stuffed them in the jar. To top it off, we gave them pieces of ribbon cut into 4 in. or so lengths and then they tied them to the top. With the right ribbon it can turn out so cute!
