Instead of keeping a journal or starting a scrap book, a memory jar is an alternative way to record summer nostalgia. If all the memories will not fit into one jar, you may want to make several for special days or outings that happened during the summer. You will need a large clear glass jar with a lid. Collect small mementos or other meaningful objects that will fit inside a jar. They can be photographs, a special rock found, something you made, or a friendship bracelet. The options are really only limited to your imagination.
