When we go looking for events to add to the Tip Sheet we happen across a lot of amazing classes, dinners and adventures–it’s overwhelming just how much you can learn, and how much fun you can have, in this city. That’s why we’ve partnered with SideTour to bring you a few of their very best, only-in-New-York experiences each week. SideTour helps connect creative people with something to share–whether that’s taking a museum tour with an art historian or attending a dinner with a South Asian chef–to people who want a unique new experience. This week we’re especially intrigued by the Moroccan henna art lesson and a demonstration in Crown Heights Thursday, March 21. You’ll learn all about the history and technique and then have your hands decorated by an expert artist. Or, take a ride on the Staten Island Ferry on Saturday, March 23, and kick off spring with a photography expedition with a documentary photographer.
