David...I think your two responses are the most comprehensive that I've read in a long time.
The fact that markets vary, depending on venue, geographic location, events, and the type of people who attend, there is no real certain way of setting a price prior to that knowledge.
But here, you have nailed the fundamentals of the individuals that might come by and look.
It is true...the first thing they do, is look inside, then come the fingers....then they turn it over and look at the foot...then they admire the form. The colors, finish, and presentation are probably the initial attractant.
A few years ago, someone posted a comment they overheard at a craftshow.....that a potential customer made to her companion...."Why would I spend Thirty Dollars on a Wooden Bowl?"
As turners...we think, "Well...do you have any idea what goes into that bowl?" The answer is generally....No...they have no idea.
They want it to be attractive....something to collect....something that will look good in their decor...something different...where obvious care went into its making. They want to see a reflection of the artist in the character of the piece.
Sheesh..I type a lot.
Ok...Shuttin' up
