I see the green beads and some of them are in a cluster/knot sort of thing?
When the necklace is straightened out, each cluster is a simple flower. They're just decoration. It's the green beads sequences that form the name.
I think this would require some research
I've been looking and looking - I've been looking for like an old crafts book or some blog that features "old timey" crafts - but nothing so far. I don't even remember which friend made it - or what school grade - if I did, I might be able to find her on Facebook and see if she remembered.
It's quite a puzzle.
