Tapestries were used mainly as wall-insulation so they tended to be pretty huge and thick - decorating them was of secondary importance - even hides of animals would have been used in preference to cold bare walls. The most common board games I've seen look kind of like a handled square cheese cutting board with a raised "fence" arround the edge to keep markers from tumbling off on voyages. The game surface was usually crisscross lines cutting the surface into regular squares (scratched in and blackened with soot) and a small pit in the center of each to keep the assorted markers, tallys and pebbles in place, or just 7 by 7 rows of pits with only a few marked off by circles or squares at corners and edges. Handles could be single or double, plain rods or carved into faces or horses. What you've done looks really good! Have you considered making a heavier table with trestle reinforcements for heavier tasks, or sawed-off tree sections for portlier folk to sit on without breaking stools?
