Susan Jion Postal, a wonderful Zen teacher, sent me a message with some things they are doing in their Sangha. She said that she is also interested in involving families, thinks we can do so based on themes found within the Zen Buddhist tradition, and sent this link to their blog ...
They have a "Zen Kids' Rohatsu Buddha-making workshop", which she calls "a perfect gift for us all at this season of celebration as the year comes to an end."
