I like A. Cohen Co., Inc., 333 Washington Street, Boston MA,
617-523-7440. In the Jeweler’s Building. They are open Mon through
Saturday . They offer a discount to students.
Contenti (in Rhode Island) is another source for supplies- will
you have a car available to you? http://www.contenti.com
Here’s one gallery http://www.societyofcrafts.org/galleries.asp
I’ll see if I can find some more for you.
