Like many creative folk, I keep a notebook with sketches and ideas for future projects. It comes in handy, particularly now that I'm trying to branch out a bit and integrate patterns and colorblocks into my newer pieces.
I have a bit of an obsession with office supplies. Pens, notebooks, folders-- they all help me create the illusion that I am an organized person. The truth of the matter, however, is that I am not tidy. I love the idea of being a neat and orderly individual and I try to get my act together several times a year. Perhaps one day I will make the leap...
My current notebook is pretty cool. The front of each page is lined, and the back has a grid. I can sketch or create patterns on the grid, and make my notes on on the lined portion.
