There is a good shop in forked river. Called quilting possibilities. You can find them on the web. They are near exit 74 of the g.s. parkway. I understand there is some kind of quilting or fabric store in Howell nj also but have never been and don't know the name. I'll bet there is something in the Princeton area too but don' t know for sure.
I'm further south than you, near Ocean City and so don't know the more northern stores.
