A board tells a different story at each end. Along its length we see flowing lines; across it we see the rings that those lines belong to. Looking at both before making a cut can suggest how to arrange neighbouring pieces.
This drawing reduces the board to a handful of strips. It is a reminder to compare the ends in good light and mark the face that will remain visible. A pencil arrow is easier to trust than a memory after the pieces have been moved.
The aim of this notebook is observation. Sketch first, label the parts, and leave enough time to reconsider the arrangement.
