Peter Nencini made a contribution to pop-up Pound Shop: 50 'Hand Werk' building boxes containing a set of materials for abstract play. His embroidery for dining chairs is also nice. The text on it is from a book about the psychological affects of domestic space by French phenomenologist Gaston Bachelard: The Poetics of Space (1958).
I like this one of a kind tiny zine from artist Misaki Kawai. Each one of these zines, an edition of 100, is completely different. It's nice to own something that was so personally assembled. Check out her many other zines for sale here.
