This started as a logo for myself that I'd scrawl in the bottom corner of a finished graphic recording-now it's a glowing flowing flick-of-the-wrist GIF as my email signature.
From your voice to my trusty Tombow marker- If you can say it, I'll draw it!
Speaking of Tombow markers, they're my go-to for graphic recording: workshops, keynotes, big corporate plans, I've used Tombow markers (with a few DuraMark's for line-work-they don't smear when used with the Tombows) from here to Istanbul and back. And they fit in a nice flat easy-to-carry flat box I found at a Michaels craft store (and add a big rubber band to keep it closed). Might be a sewing box but works for me.
And when I get to a job, I open the box, roll-up my sleeves, and arrange those markers on each side of the box-cool colors on one side, warm colors on the other. Kind of a personal ritual that gets me ready to draw, plus a little show that tells the crowd I'm super organized and not messing around-LOL!
