On her return to New York, , Miller wrote to Grüne-Yanoff in Stockholm regarding her visit there. After several rounds of correspondence, the pair developed a vibrant collaboration, combining each of their respective studies of place, body, and language into a discussion on existence. As her contribution, Grüne-Yanoff produced threaded and textured responses in written and visual form, mining inspiration from the content of Miller’s letters and her own reactions. In December Letter, MLM-JGY (2014), Miller wrote, “I love how our letters have become material objects, how they have been embellished with wings and also penetrated by thread; flight has been enabled and disabled by what you’ve done.” The letters, now turned into artworks, give physicality to statements, feelings, and ideas. They give form to spontaneous thoughts and unforeseen reactions.
