Even though Ink About It is not too far from me, I haven't made it there yet. If you end up going, let me know what you think!
I have managed to hit every LSS in NH, as far as I can tell, but there quite a few in MA I still have to get to, ironically. Sounds like a scrap store tour is in order. I have been to all 3 mentioned on this thread once and I'd like to get back to all of them eventually. I had DH in the car for 2 out of 3 of them and I always feel guilty spending too long in there! Another one I'd mention is Absolutely Everything in Topsfield (my closest LSS). I don't let myself go too often because it seems I drop at least $50 every time I step in the door.
Buffy - I am sure the Tim Holtz classes are sold out. My LSS used to get him once a year and his classes sold out crazy fast. I never took a class, but I met him at the store when he was doing demos. Very cool!
