From “The Density of Light” by Gabriel Dawe.
“The thread is regular sewing thread, 100% polyester, and it comes in a wide variety of colors, so I don’t do any of the dyeing myself. Usually each color is a unique long piece of thread, held in place by mere tension. Sometimes I use more than one spool of a certain color, but I just tie together the ends and continue with the installation. The color mixing really occurs in the space, a byproduct of the process.”
