Joyce posed a question in a comment that is so good I decided to make it a blog post where we can all see it and share answers.
"How do y'all store or display the postcards received? I, of course, want to keep the ones that come to me, and of course won't let anything happen to them, but I'd like a creative way to store/display them. Can you share some of your ideas with my please? Thanks"
