So I noticed that the glue joints seem closer together in some parts of the cutting board than in others. I can feel the glue lines when I place my hand on the board. some places the glue seems to be missing and there are small holes in the glue joints. sanding it down would make it smooth however what do I do about the glue? Do I apply more glue somehow? What about the cracks? I'm worried it will get worse. Your help is much appreciated.
