I'm almost wrapped up with filling voids, bark inclusions, and knot holes in the boards for the bookcase. If our garage was climate controlled I expect this process would have gone faster; the same could be said if I had more horizontal working space for staging and filling. Once everything is done curing I should be able to go back over each board with the finishing grits to reach 220 - after that it's cutting to have a plumb edge and to create the shelf supports.

Since we're popping the grain in between sandings (spraying lightly with water and allowing to dry, which swells the softer grain and allows for a smoother finish) I've been able to see what these will sort of look like once finished, but the small bits of epoxy that made it over the edges of some of these really make the grain look downright sexy.
