Give it a good sanding then step into the sunlight to check the progress.
The sunlight trick may seem rather simplistic, but once you try it, you will see exactly how revealing it can be, far more than a lamp.
If any irregularities are found, simply go at ‘em with a finer grade paper. The finer grade removes lumber at a much slower rate, allowing better control of what’s happening.
Now a finish sand of the whole body is in order…
check it closely in the sunlight… you may find where a piece of wood may have been on the work table and left a calling card..
