It's a piece of Walnut branch it fell off the tree about 6 months back and has been on the pile to be cut up since it fell foul of me and the chainsaw on Saturday so its still a bit green.
This is the second one I have had a go at the first is a lot smaller and very basic more of a bantam egg cup size.
Thank you Woody I have got the day off on Friday so there could be a picture up on Saturday have got to make some coaster's for a friend so it could be them but they will be a bit plain with only a groove on the top
There are wine glass shapes, goblets and chalices [and probably more], I'd say that's heading toward a chalice [wider I think] and as such it looks great, especially the wood choice.
