Spirithorse I have made enough of these type to have a fair idea what it will look like. I have trained myself to see what the end result of the blank should look like when glued up. I still get surprised now and then however. As for documentation I have not really thought about doing that, the closest I have gotten to doing that is something like what I just did. I showed the blank, then the pattern and the pattern placement and then the bowl made from it.
