Known for their small size and oilcloth cover, moleskin notebooks have been beloved by creative minds - artists and writers in particular - since their invention. Compact, portable, and made with archival paper, the treasures contained in their pages are usually private and hidden.
When I was a practicing artist, my 4"x6" notebook went everywhere with me. I sketched lines, colors, ideas, making notes and trying out different versions of the same topic before committing my composition onto a larger, more expensive medium. Here then, are a few exciting samples (I have not scanned my own.)
