needle felting is a very basic repair and crafting technique. i first discovered it in the diy-exhibition in frankfurt and here is a link to the project i saw there (thanks to verena kuni for providing the link).
the workshop is part of the exhibition gute ware lobt sich selbst at kunstraum22 in cologne.
bring your favorite sweater and repair it if has wholes or participate in the creation of collaborative piece of art. ralf schreiber is also joining in and will bring some electrowool and eventually we will also create some felt-circuits.
