I really missed the ability to sharpen a pencil properly, which means giving it a long, tapered point with a knife. I obviously couldn’t travel with one, and I didn’t feel I could ask the ship’s crew to borrow one.
I also rediscovered how the consequences of dropping a pencil are not the same as those of dropping a paintbrush (Clue: the tip of a paintbrush doesn’t shatter). Fortunately, I packed some spare pencils.
I made one innovation too: using dental floss for a measuring tool — comparing lengths and distances relative to my source images on the ipad) and for setting a plumb line.
I know have several fresh sketches in the book and will continue to add to the collection in future travels. It’s a great way to pass the time without making a mess. And unlike painting there’s no clean up involved.
