The brightest thing in your front window is probably the sign that says, “Open.” That’s a crucial bit of information you need to show the world, but are there other messages you could get in front of the casual viewer. How about “Books Hot Off the Press” or "Readers Welcome"?
Cinema-style signs are available at home decor stores and online (see here and here... and here). Be alert when you shop for light boxes. Some are powered by batteries or a USB connection; others can be plugged into a wall socket. Be sure you chose the option that’s best for you.permanent sign to announce “Live author 7 pm” or “Free recommendations.” Those will never go out of style. (Hat tip to John Mesjak for this idea. Thanks, J.)
