I started carrying one of the small, cheap Moleskines around several years ago. Gridded or blank, it’s small enough to fit in my pocket and carry _every_where. I use it for random jottings, making impromptu bookmarks, shopping lists, phone numbers, ripping pages out when I want to give some one some info, writing stories when I’m bored, etc.
Just recently I started using one my daughter made for me by hand …
… I love it!
