manzanita branches!

So I wanted to get your girls' opinions as well, as I have already asked over there. We are getting married at a historic museum that has black walls and ceiling. has white boxes around the walls filled with history dolls and we are at a loss for what "feel" we want to portray. We up until yesterday thought yellow with demask. but yesterday I found burlap and began pondering my very initial thoughts of rustic with a slab of wood in the center of tables. Either way I will be using a chalkboard for table names. I will post the link to FB where there is all kinds of pictures of the venue and if you could please share yout thoughts on if you think damask black and white with yellow would look better or a more rustic feel with yellow. Also. please note that we cannot use flowers because it is in a museum and they don't want to attract bugs. We are thinking lemons/limes and/or those jelly balls with a floating candle or 1 stem daisy. 

Thanks so much for your help girls!
