Here is a useful and simple tip. Empty your trash can frequently. I was stacking just 2 1/8" boards today and I noticed after cutting around a small piece that the piece was barely hanging on. I then turned it over and
to my dismay, I realized the piece from the bottom board had just been discarded with another piece that I had just tossed in the trash can. Of course, I hadn't emptied my trash from the last several projects so there were hundreds of small pieces in there. I searched for about 5 minutes and said the h--- with it. If I would empty more often I would have much less to go through when accidentally discarding a piece. My only hope now is to try and duplicate the missing piece later and glue it in and hope like heck it matches.
