Here is my first finished bowl/plate project out of walnut. I still have some light sanding to do. The darker stripes are in the wood itself. At first I thought I somehow caused that while sanding but it is smooth. The grain of the wood looks like it may still have some fine dust in the pores of the wood. Do I need to do something with this before I apply a finish. Can I wipe it down with a lightly damp cloth or will that raise the grain too much? I plan on buying some kind of oil finish tomorrow to put on it. What looks best on walnut? What is the best way to apply an oil finish? Brush...cloth?
