The bottom photo is a detail of one of the silk-tie-embellished circles. The rambling yarn is also embellished to the felt background. Some circles are completely covered with silk and some are covered only in the center. The fuzzy circles are felt that has been embellished from the back side.
My third piece in this series will use the same felt colors and circles, but I haven't decided how to "embellish" them. I may try hand embroidery.
