My new business cards, which I ordered a week or two ago, finally arrived today. I had run out of my last batch of 250, but it took 2 years. I don’t work with outside vendors very much so I don’t have too much of an opportunity to use my business cards, but I don’t like them sitting there going to waste either. So I use them as bookmarks when reading my books. One card per book, and then a fresh card when I start a new one.
And of course, if someone asks me for a card, I now have one handy.
