Everyone brings their own craft supplies, though sometimes some people have extra supplies they don't mind sharing. We've had people painting, drawing, coloring, sewing, beading, knitting, kite-making. No craft too weird. Craft Day is for creative people to gather in one place and keep each other company/ inspire each other while we hang out and do creative things.
The intention of this meetup is to allow people to work on projects together, to inspire each other to work on that thing they started or meant to start and then shoved into their closets and forgot about, to get excited again about creating, to ask someone else for ideas about something they're stumped on, to share skills and knowledge, to meet new people.
We've built up several regulars who come to every Craft Day they can, and we get new people every month. Don't be afraid to come if you don't know anyone or can't find a friend to come with you.
