I really love this idea and I think that I will go looking for a jar or two for next year. It might be something for my sister as well! You know how it is when we start running out of ideas!!
I think that this would make a great birthday present for a senior (if you are in need of an idea) Every time they remember a wonderful memory, they could write it down and slip it into the jar. On a family occasion, each memory could be shared!
