Here are some places you can go, who are happy to have electricity, and are happily up and ready to serve you:
Rosen & Chadick
NY Elegant Fabrics
Fabrics & Fabrics/ Lace Star
I haven't heard from many of my November 2 tour participants, but if any of you want to shop tomorrow, I do know that at the very least, these stores are open and fully operational!
Some trains are running, making it possible to get there, too (depending on your starting point), although the mood of the city isn't really supportive of fabric shopping right now...
Just wanted you to be aware of the possibilities!
