This was a somewhat difficult challenge for me. I am somewhat Canyon deprived having not really had a chance to view a canyon in person (until my trip this past weekend to Sedonaa, AZ). I knew I needed to get my quilt done before that trip.I looked up the definition of canyon - " a gorge or ravine, esp in North America, usually formed by the down-cutting of a river in a dry area where there is insufficient rainfall to erode the sides of the valley" and thought of the action of a river cutting into its environment and reshaping it over time and getting deeper and wider over time. I portray this time sequence. I started off with hand running stitches in white on a dark brown solid background going through the background and the batting. I then added more definition with rowns of couched yarns and cord . I added a backing and quilted it with straight stitches using heavy pink cotton.
