Arts & Crafts Material Swaps in Philly?

[LisaK.]

A few years ago I went to a couple of swap meets put on by Handmade Philly at Moonstone (formerly Robins Bookstore). At the first I found a wealth of papers for collage and other materials. I check back at their website from time to time and haven't seen any listed. Does anyone know of any others that go on? Even if it's just at an artist's home studio, I'd be be delighted to bring a little something to swap. Thanks!
