I did come across this very interesting interview with Jeff Pike, who is the VP of Sales and Design for Great Coasters International, one of the most popular wood coaster design companies out there today.
While everyone has seen interviews before, I think that this one is the correct way to do it - asking unique questions that elicit more interesting answers. Like, for instance, the outline of Jay Leno's face was inspiration for a coaster in Holland?
You'll have to read the interview to know more. Check it out here, on the No Joe Schmo blog.
