Since posting Picture This LIX, I have come across a few additional images of tables incorporating open- and blind fretwork.
The juncture of the rail and leg of the table in figure 1 is a rather clumsy combination of open fretwork and carving.
The blind fretwork on the mahogany table in figure 2 presents seamless decoration across the rails and legs.
The card table in figure 3 is similarly decorated with blind fretwork. Note the small curlicue in the fretwork veneer at the top left of the leg has popped off (double click the image to enlarge it).
