That’s an interesting idea. I’ve seen a lot of leaves and stems left over, so it’s not hard to gather them. Just make sure the pieces are clean and dry before you glue or bind them, and use a natural adhesive if you can. If you add some paint—preferably something recycled or made from earth pigments—you’ll keep it eco‑friendly. It could be a nice way to recycle and show the garden’s life in a new form. Just take it slow and test a small section first.
