Thank you all very much for your lovely comments. I have not really carved that many spoons, but I have a creative job and make various things every day, I think the skills are transferable. The more simple spoons took 3 to 4 hours to make and the spiral one about 10. The Yew was green when the spoons were carved and although the wood is toxic it is not as toxic as the green parts or bark. They are mostly decorative but can be used for the occasional scooping of jelly without too much danger i think. The tools I used were a Mora Miki, Frosts spoon knife, Dremel drill and sandpaper.
Thanks again,
Nigel
