I am building a QSWO bookcase, with a mission stain. I hate the thought of
paying for QSWO shelves when they really won't be seen anyhow. Is it
reasonable to stain red oak to fit in with white oak?
Anyone with experience care to relate what he did?

I just built a walnut bookcase. For the shelves I used red oak plywood with
a 1" strip of walnut in front. I originally intended to stain the oak to
"match" the walnut, but the contrast looked pretty good, so I went with it.
Could do the same with unstained red oak and mission QSWO. Any comments?
