This is a Zentangle Compass Rose. It took me four weeks to finish, and I am very happy it is done. I made so many mistakes, from wobbly lines to every sort of inexactitude, but it doesn't even matter. Art is partly telling the critic inside to go away because I'm happy. And Zentangle always says, "No Mistakes." Plain persistence gets you a long way.
Of course I was drawn to this idea because of the hundreds of hours I spent on night watch in the waters off Florida, the Bahamas and the Caribbean. Warm nights with silvery black water as far as you could see in every direction. For my four hour watch, the tiller in my hand, my eyes wandering up in the sky and the sails, then always coming back to check the course. To be on course, to know the direction. No mistakes.
Steering by a star made it all easy. They taught me to line up a mast or a cross beam or the pointed top of a sail with a star. Then just keep them lined up. It's easier than trying to keep the compass needle lined up on a certain degree on the compass rose. Steering by one star works well for a long time. Eventually you have to pick a different star if you want to stay on course.
