As a continuation of the last post, about how to do the bookmatch of the walnut back. It is somewhat difficult to see what the bookmatch would look like if one cuts off varying amounts of sapwood, or angled the boards a bit since just overlapping the boards gives a pretty muddy picture. Something I have thought of trying, since it is hard to visualize just overlapping boards, is to do the bookmatch ‘photographically’, by cropping a picture image and pasting the two halves back together. It works pretty well, and is not hard to do. So, continuing the ‘how to’ question, we have:
1) The full sapwood
2) smaller sapwood
3) really small sapwood
