Napkin Holder, for camping so the napkins don't blow away. The base is 6.5 X 8.5 and the top piece is 2 X 8.5. The dowels are 1/4", spaced 7.25 center to center. Holes in the top piece, where the dowels slide through, are 5/16. Material was 1X pine, although any type of 1X would work fine of course. I don't see any reason a 1X8 could not be used for the base and left full width.
