My favorite item in this exhibit was Palace Yurt, by artist Janice Arnold. Created within the space of the museum's conservatory, whose domed roof resemble the framework of a yurt, this installation pays homage to the nomadic tribes who first created felt. Designed as a total environment, Arnold made this yurt out of a combination of gorgeously luxurious Merino wools, silk, metallic fibers, and sheer fabrics. Unfortunately, I was not able to find any images of the finished yurt, but below are some of Arnold's sketches and examples of the felt created for the installation. You can read more about the creation of this piece on the Cooper-Hewitt Design Blog, with the sketches here, and a video of the making of the yurt here.
Examples of the felt that was made: it has a base of silk gauze with wool, silk, soy, and metallic fibers felted in.
