Scents & Sensibility was popular back in May and June

Eclectic is the word for the skills one can pick up at Brooklyn Brainery. The Gowanus center of learning is dedicated to all things brainy, from beekeeping to holiday upcycling to world dumplings. The Brainery was started by a couple of people who were sick of paying bookoodles of money just to learn stuff. And the mission holds true: Most classes start at around $10, and the offerings change every month. So by that measure, a $25 gift certificate should put a curious friend on the path to some serious enlightenment. One of our favorite subjects from the past year: How to make irrational decisions. Gift certificates start at $5, and they never expire.
