I choose to only use the 'Map a Day' style of journaling as stopping to sketch was unrealistic atop a mountain in the chilly wind. I waited to illustrate my story when I was snuggled warm in my tent.
I admit, the challenge for me was to be drawing cartoon style images out of my head. But the end result is so playful and quite humorous. And it certainly tells my story! Like anything new, practice will make it easier.
