H. H. Windsor, Mission Furniture: How to Make It…
“ Beginners are prone to underestimate the importance of getting all the mill-marks off before putting on any finish. When boards are planed at the mill the planing is done by means of two or four knives revolving above or below the board—sometimes both above and below at the same time. These knives leave the surfaces filled with little ridges and hollows across the grain. These hollows, though they are hardly visible [52] to the eye on the unfinished surface, show up as ugly streaks upon the surface after it has had a finish of stain and filler applied. ”
