Thanks again Pontiac,
Generally, they start with a piece of material, that evokes a thought, that moves towards a concept, which turns into a vision, from there a plan is made.
Now then, when the thought, concept, vision or plan go south, is when the improvising starts.
For me, it is common to make changes as things don't look like whatever was in mind.
Put a couple coats of satin varnish on the wood and some scorched linseed oil on the copper today.
