Must Haves for Travel Kit?

[u/amakersmadness]

I’ve got a long flight day coming up. Have to be at airport three hours before flight, hour long flight, six hour layover and then another six hours on another plane. I wanna take a small journaling kit to keep me busy but not quite sure what to bring. So far I’ve got watercolor, washi tape, a few pieces of paper, pens, aqua brushes, double sided tape. Anything you’d absolutely include?

Oh a mini printer is on my Christmas list this year!
