Custom Bookmarks: Download samples here
In addition to the usual media kits, press releases, and postcards that are often used by authors to promote their work, I have also found bookmarks to be very handy, especially as FREE giveaways at book-signing events. Although a "potential" buyer may not buy your book initially, they will grab anything you have lying on the table. Later, they will use your bookmark in another piece that they are reading. And every time that they open that book, they will be reminded of yours. I have designed several of these for myself in the past and just finished a batch for fellow Christian CW author Richard Williams. It is also a good idea to post e-versions online so that visitors can print them out from wherever they are. Remember, the "power of suggestion" can be quite powerful.
