Thank you @erikah. Yes I agree, people have different tastes. For me Greece had lots to offer. I especially appreciated the variety, from the historical structures and museums to the brilliant white painted villages built onto the cliffs of the island of Santorini. You can make a sketchbook be whatever you want. I have some sketchbooks that have lots of notes and commentary, with pasted in receipts, stamps, anything that looked interesting - like a scrapbook. I paint with watercolors in some too. I'd say just do it for yourself and don't worry about your skill level.
