looking for opinions:
i will be making set of shelves with some beautiful walnut lumber i recently acquired. the wood does have some color variance, but is mostly very dark, with nice grain. would there be any advantage to using a walnut stain (would that even out any color variations), or will i be just as well off with a simple varnish finish.
i have never worked with walnut before, and i plan to make 2 test pieces this weekend. one will be stained & varnished, one will be varnished only.
i realize that this is probably a matter of personal taste, but i would appreciate any opinions.

thanks
