Here is a 1974 illustration that shows an appliqué or embroidered heart on the jeans.
During the 70’s, fashion was very much about “expressing yourself.” A new pair of jeans, jean jacket or blue chambray shirt was an empty canvas for doing just that.
In this illustration, you will also notice a girl holding a Raggedy Ann doll. Raggedy Ann has been a favorite American icon for years. That must be why I chose to embroider her on a pair of my jeans in the early 70’s! Her face was down near the hem of the pants. When it came time to throw out the old jeans, I cut Raggedy Ann’s face out and tucked her away.
