I saw elder and made whistles

I was at the Forest School Association national conference in Shropshire over the weekend  and saw how to make whistles out of natural materials. My dad used to do this but I never knew how it was done. It turns out to be quite easy. You need a knife, some elder and any other green twig. Oh, and a little know-how…..

As it's half term I've been leaving them for children to find. If you find one you are welcome to it.
