I recently hosted a material swap through the artist_cards community (see the picture below) and it was such a success that I have started a new livejournal community to help facilitate future swaps with interested artists. Please come check it out.
A brand new livejournal community that helps artists to trade materials that they have on hand, but have no real use for, with other artists.
Any artist who wants to swap materials is welcome to join. : )
We are currently taking sign-ups for the July/August swap.
Cross Posted around a bit, so I apologize if you are seeing this more than once.
