Today I attended Mike Rowdy's webinar titled "Reflective Travel Sketchnotes." The idea is that during travel, it's not always possible to sit down at the end of each day and draw a sketch. Either because the day was very intense, or because you now have two children.
In this case, you can take photos, make text notes, or record something on your voice recorder at the end of the day to capture moments that can later be transferred into a sketch.
The second part was about step-by-step instructions and an example of how to create a travel sketch. This, by the way, turned out to be quite similar to how I made my own travel sketches.
