I make these combination scrapbooks/sketchbooks for most big projects, and put all my bits of inspiration and reference and ideas inside. Around here they are affectionately known as my "old-fashioned Tumblrs".
This one I made for my next series of work, inspired by Perrault's fairy tales, kimonos, and this quote from Wuthering Heights (it's in a place of importance, taped into the first page). Wild beasts & fair maidens, the best company I can imagine.
I have a handful of big projects I'm working on right now & can't wait to share dispatches as I can!
