This sounds like a good idea to me. Here's the only good example of a border I have at this time. You have to make the stamp, but it may give you ideas on how to use stamps you already have. I'll put up more when I get good photos of them. This can be a continuing thread, so be sure to load the pictures using the "Additional Options" at the bottom of the new post page rather than linking to a photo somewhere online. If the online photo disappears, it also disappears from your posts. If we get enough examples, I can add a link in the How-To FAQ thread.
A little later: I remembered I had a couple samples kicking around my desk that I banged out one day to test a couple ideas. I scanned them in. Here they are, too.
