Reflection is a marvelous thing.

In a fit of revelation I realized that the doors themselves provide a barrier to the dust of sanding the jambs, so after running masking tape over the gap b/w door and jamb on the interior side, I sanded and oiled the jambs of these doors to the terrace.

Afterwards, I removed each door and set it up on horses to sand and oil.

The sea wind seemed determined to catch the dust I had figured out how to keep out of the house and wisk it right into the opened doorway, so I hung a dropcloth over the opening.

Upon reflection, the doors DO look better, and ARE better, even than new.
