Lately we've gotten a flurry of orders from New Jersey, from eight towns in particular: Teaneck, West Orange, Union, Passaic, Cherry Hill, Elizabeth, Westfield and Edison.
I don't know my way around New Jersey, so I am at a loss to conjecture what these towns have in common. But I can get a very vague picture of Jewish communities based on the tallit and tzitzit products they order.
At a glance, what I'm seeing from our customers in New Jersey are a lot of wool tzitzit (i.e. tallit katan) and a lot of blue: about half of the tallits purchased have blue striping and a lot of New Jerseyans are buying Ptil Tekhelet tzitzit.
