Lisae,
I'm sorry, I meant to say that they were PIECED in the 60's 70's. Some of the material could have been as early as the early 50's. She saved every scrap of fabric and all of our old clothing. Now I'm not giving away my age but I haven't worn kids pj's since the late 50's early 60's and I know some of that material came from some of mine. So you may be right on the mark with your dating. Glad you liked them and I could be of some help.
