On the train to New York City for 24 hours. Here's my absolute bare bones journal kit. I also have napkins to glue on as well as wipe off excess glue and burnish with. I can toss/recycle them as I go.
In the ziploc bag are background papers, collage ephemera, stickers, glue stick and three pens.
Not much but it keeps me sane!
