That sounds like a description from a novel. Beautiful.

You can absolutely craft at least the palm leaves. I was raised Catholic, we’d weave crosses, stars and headbands for Easter every year — one of the very few fun things about the Catholic church.

Raw fibres, like reeds and stems, shrink as they dry. Tight crafts go loose and you have to do them all over again. Palm leaves (depending on the type of palm) are good because they don’t shrink that much and tend to stay green longer. The palm baskets I made after a wind storm held up for years.
