Update

So...where was I up to?
I have been making hollow pieces for a little while now. Mainly by constructing them out of two halves.

Never quite satisfied, I continued experimenting. My aim was to make the items in one piece, creating the opportunity for a more organic, less constructed style...

Above are some very rough and ready early experiments.
I finished this little necklace yesterday.  I'm happy with the shape and the surface pattern and plan to make more miniature vessels in this style soon.
