Blue images in each of these quilts were created through the cyanotype process discovered in 1842 by English scientist Sir John Hershel. The process involves treating cloth or paper with a solution of two chemicals (ferric ammonium citrate and potassium ferricyanide) that, when exposed to ultra-violet light, develop an intense blue color, also called Prussian blue. To create images, one places either objects or film positives/negatives on the treated material. These prevent light from activating the chemicals and thereby produce negative images of themselves. Thorough rinsing with water halts the chemical process and makes the image permanent.

Members of Fiber Works experimented with leaves, grasses, needlework fragments, silverware, and photographic films to make their cyanotype images. To complete their quilt compositions, they added materials enhanced with other surface design techniques such as shibori dyeing, monoprinting, digital printing, and painting as well as appliqué, embroidery, and quilting.
