There have been a number of recent articles about writers using Pinterest to promote their interests and their books.
I set up a Pinterest account ages ago and let it sit. In random moments I would remember it, add a pin or two, then sock it away for a few months. If you’ve been following my blog, you’ve spotted a few posts about the location of my crusader knights on different dates as they journey from Southampton, England to the Holy Land in book 1, Men of the Cross. I’ve also mentioned a few locations in book 2, For King and Country. I’ve included pictures on many of those posts. Eureka! Why not use Pinterest to post those locations, too? What a concept. (Not original, I’m sure, but still… )
