This is a simple headband, topped with the with the flower of your choice. I recommend the Pacifier Clips: Flower, by Susan B. Anderson (knit) or Slinky Crochet Flower by Teresa Richardson (crochet)
The pattern uses Elizabeth Zimmerman’s “cast off” to achieve a bind off that matches long tail cast on. The bind off can take some getting used to, but once you get the hang of it, you’ll find it stretches and looks nearly identical to long tail cast on.
