You need the burlap runner.I think you should choose one color for the napkins and use the other color in the accents. Purple napkins pink flowers. Maybe alternate the table per color vs seat.
whoa I really like the look of this!! solid navy with the hint of gingham... not sure how we could pull something like that off, but I'd be ok with ditching the Ikat idea for something like this (and i assume it would be easier for rental)
