I love the continuity of the grain on a one piece top. When book match is done "right", it can be way cooler than a 1 piece IMO, but the ones that are matched correctly are, I think, more rare than the 1 tops (unless we are in Private Stock territory where most of the book matches are real close to matched if not fully matched). I have about 100 silk shirts and I won't buy one if the patterns don't match up down the button line or the pocket (if it has one) does not match the pattern it is laying on top of. Had a couch refinished a few years ago, and I let the lady who was doing it know, that if those lines did not match where the fabric was going to come together, it was coming back ;~)) So I guess I just have an issue with stuff matching! More relaxing on my eyes me thinks!
