As the Project Mah Jongg exhibition comes to a close, join us Sun., Feb. 6 for a 6-hour-marathon to raise money for the Museum of Jewish Heritage. The entrance fee is $25 and the event lasts from 12 noon to 6 p.m., but you can play for as long or short a time as you like. Ask your friends, family and co-workers to sponsor you. Minimum donation is $18. Throughout its history in the U.S., Mah Jongg has been at the center of women’s gatherings to raise money for worthy causes. Take the day to celebrate the role of Mah Jongg in the Jewish-American tradition. We will have raffle prizes, theme hours, and special guests. When you register, you will be asked your skill level to allow us to match you with the right players. Have sponsors who don’t want to donate online? E-mail mahjongg@mjhnyc.org . Bring all non-electronic sponsorship money with you when you arrive at the Museum on February 6. E-mail mahjongg@mjhnyc.org with your questions. And thanks for helping us out.
