I'd go for the luxury book for my iphone 6S plus.
Specially in Black exterior and chocolate interior. I really like the leather look and sturdy material to protect my phone.
I'm buying a new house and can't justify another Apple expense so it'd be really nice to win an an Apple Watch as well and the Pad& Quill's accessories.
I'm really enjoying the look of the Timber Case! I would use it for my new iPhone 6s Plus. My favorite features are that it looks sturdy, up to the task at hand, and quite attractive.
By far my favorite Pad & Quill feature is the wooden frames inside the Pocket Books. An Apple Watch stand made with the same craftsmanship as one of Pad & Quill's iPhone cases would be wonderful. The Timber Nightstand, please!
