Ohlone baskets in Coyote Hills Regional Park, Fremont, CA.
Dogbane or stinging nettle twine is useful for lashing the tules to the frame. A lesson plan for creating the cordage can be found at the following link.

This was taught to me by Dino Labiste, a Naturalist with the East Bay Regional Parks District in a class entitled, "Ohlone Tools and Games for Your Classroom." While it appears this class is no longer being taught, a resource page can be found on the East Bay Regional Parks website.
