Lenova Yoga. Small, light, holds a charge forever. Can be used as a tablet too. Easily goes from the patio to the coffee shop and even to bed, when I just have to finish one more scene before closing up shop.
Blue Sky Spiral Planner. There are tons of beautiful high-end planners out there, but this one does the job for me and comes in under $30. I do most of my planning in a bullet journal. I use this one so that I can see a month at a glance and tag specific dates with events. The one in the picture is last year’s. I linked to a 2018-2019 Academic Year in blush which is prettier anyway.
Pentel Energel Pens. Smooth and not smeary. I’m using a blue one at the moment, but they are available in all sorts of vibrant colors that really show up on the page.
Shatterproof wine glasses. I don’t know why I can’t hold onto a wineglass outdoors, but these are cute and unbreakable with a thumb indentation that helps you keep your grip even if your mind wanders.
What are your indispensible outdoor writing tools? Are you participating in Camp NaNoWriMo?
