When I was a girl, the levels in Primary for girls were called Larks, Bluebirds, and Seagulls. You had certain tasks you had to accomplish at each level also.
I spent a summer completing it. I did lots of the work while sitting up the discarded treehouse that my brother Lyn and the neighbor boy Freddy Vergine had built. Then they built a better one and gave it over to us younger kids.
I have never been a real star at embroidery. I don't do it often now - mostly just doll faces in fact. I'm not sure why I chose those colors either. I suspect someone gave me the thread. This one is attractive by virtue of being pressed and mounted and framed - and vintage!
But the message certainly does have merit!
