If I have to use filler (even a little bit) am I a failure? Not as fatuous as it sounds, actually. I had a friend who reckoned that the less he spent on filler, the more skillful he was becoming at woodworking. OTOH another friend of mine had a cabinet full of different types and colors. His philosophy was that getting close and then tuning up with filler was entirely legitimate and, in fact, part of the woodworker's craft. As long as it's well filled, the look achievd is the important thing. (BTW I am including sawdust mixed with glue in the definition of "filler".) Personally, I'll use a little as long as it isn't noticeable.
