I've always wanted to make Lei but I felt the same way, I don't have enough plumeria flowers. But Now that you mentioned it, I do have plenty of different flowers (re: gladiolus, Daisies and hibiscus and if course tons of leaves).
I need to research what tools I need to make a lei and just the basic step by step process. Maybe there is a simple lei making video Hetty that you can recommend we watch. I saw a you tube video at one time but I still am lost.
