If you're looking for a creative Christmas gift or even something for yourself, the t-shirt sketchbook is a good one. Pukka/Dank manufactured this t-shirt sketchbook that contains 170 pages for you to get your creative juices flowing. You may not have to be a t-shirt designer, but it'll be fun doodling all over while helping you get into your zone. For $15, I say it's worth it, but then again I love sketchbooks and fill them up pretty quickly.
