Reserved seats/table

I posted previous about how to designate reserved tables for family. We are having ceremony and reception in same location. Our guests will be sitting at same table for both events. We want to reserve approximately 4 tables for family and close friends. We are not having assigned seats or a DOC. I was wondering about placing chair sashes on the chair of reserved tables only. Do you think this would be ok and/or look ok or should I do a paper or wood sign. I am enclosing a screenshot photo of venue and samples of each idea. Also which table cloth for sweetheart table? Our colors are rose gold and various shades of gold decor. Ivory table cloths with burlap and lace runners. Ivory, petal pink, charcoal grey. Rustic theme
