I am preparing to stain an old oak table that I have sanded. Some old stain still remains. It looks like it might have been a cherry stain. The problem is that some areas have sanded out lighter than others esp. where I've sanded more enthusiastically. How do I even this out when I stain it? Do I need to apply a stain controller or just try to work the stain with a second coat in the lighter areas? I would like to get it as even as possible. By the way, I'm planning to stain it a cherry color. Appreciate your comments.
