That is the question. 
I have noticed some "round" or"soften" the edges of each piece while others do not.
Do you round or choose not to and why? If you don't do Intarsia but enjoy seeing it, which look do you prefer?
It All depends on the pc and the effect you are after ,some artistic freedom to modify your own view ,of the work you are trying to present .Nothing is cast in stone ,Even patterns are usually modified ,by accident or on purpose ,only the artist really knows which.Thats what art and craftsman ship ,are all about ,indivual taste ,knowledge ,and some times just dumb luck.Wood and grain choices ,the sanding ,carving ,softening or hardening specific areas ,all part of the process,choices make or break a presentation ,from good ,fair ,classic ,extraordinary or designer fire wood !!Controlling the focus ,acccenting the certain important details ,comes with experience ,skill and real talent ,talent is a free gift ,We all have it in something ,If it was all the same ,there would not be the need for all of us!
