So what states is this done in? Texas, obviously, and Louisiana from AOII Angel's comment. I have never seen these in middle or east Tennessee or in Atlanta when I lived there.
The Florida Panhandle, circa 1999. I have a picture where the mums on my dress are as about as big as my hair. We didn't call them "mums" at the time, but now they do. Little teddy bears, raggedy Anns.
