leah could give you an "official" answer but here's what i say...
first, this is from the website (to give a sense of their mandate)
We're a small (and growing) grassroots crafty collective rebelling against the culture of mass production. Not only are the things we create our own, but in this glossy, fabricated world, the simple act of creation is transcendent (i.e., we make things because it makes us happy).
but on more practical terms, the church meets monthly (or almost monthly) to either do unstructured craft-ons (ie. bring something to work on and we'll make our crafts while hanging out) or to have someone teach a specific skill (spinning, bookbinding, crochet...)
all these gatherings are free but donation of money for materials supplied, or donation of materials themselves are always accepted.
it's also pretty laid back and fun.
this next month's meeting is an unusual one because leah is away on tour in europe with her band and we (she, jen anisef and myself) wanted to do this craftchat thing ever since we got back from pittsburgh a month and a half ago.
does that help? if not, fell free to ask more questions.
