Remove the dough from the refrigerator, and unwrap. Cut the dough log into thirds, and each third into 12 slices. {I cut each third in half and then in half again and then each of those halves into thirds to make sure I'd get 3 dozen cookies (
see diagram). You can cut the log into 1/4-inch slices it you don't need and exact number.} Lay the slices striped side up on the prepared baking sheet.
